Fruits of our labors even if some took “almost” a century

I’m always so glad when the Byzantine gladiolus flowers this time every year. But doesn’t that face look a tad grumpy?

Byzantine gladiolus funny face

Starting from just three or so pass-alongs corms, it multiplies every year, so it’s actually very happy!

Maggie rose is looking mighty nice, too.

Still, she’s a little out of sorts since she came down with a case of powdery mildew thanks to cool nights and moisture in the air.

She’ll work it out herself without medication, but if you’re worried about it on your plants, check out neem oil or Serenade. Just don’t apply in the heat of day and don’t use Serenade when the bees are active.

Up the street, an Agave americana is about out of time, though it won’t relinquish its claim to that corner for a century or more, thanks to its pups. And their pups. . .

century plant bloom stalk

Coincidentally, it sent up its final comment just as a Central Texas Gardener Facebook question came in about century plants. So, this week, Daphne answers: does it actually take a century to bloom? Nope.

Hella Wagner shared some pictures of her plant’s glorious ascension as the mother plant died. Daphne explains the process, and how the bloom stalk itself can even be dangerous.

My yuccas up front (Y. pallida and Y. reverchonii,) are reaching for the sky, too, but they won’t end their life with this springtime bloom.

Back to agaves, Daphne makes this deer-resistant, drought-tough genus her Pick of the Week. There are many species and cultivars in various forms, colors, sizes and habitats.

Agave shawii 'Blue Flame'

Mostly, they want good drainage, though my A. celsii does fine in my island bed that I’ve gradually amended with compost and mulch.

Agave celsii

Do look at their cold hardiness. I fell in love with an A. celsii ‘Tricolor’, as it was called then, which is rated for a zone or two just warmer than us. First crazy freeze and they were mush. My regular celsii didn’t fare well in 17 degrees but did return, just slightly modified.

Do take a serious look at their mature size, too. This cute little A. americana will grow up fast, and it won’t take even 10 years!

Recently, I added a calamondin to a patio container. We love the fragrant flowers and can’t wait for its slightly sour fruits a few months down the road.

In the ground, my Satsuma ‘Mr. Mac’ is going gangbusters, thanks to the temperate winter and a little high nitrogen fertilizer in March.

Why plants freeze|Greg Grant vegetables

My crinums don’t look so hot right now.

Frozen crinum leaves
No problem: I simply cut off their mushy leaves and they’ll rebound pronto. Although things have been rather tame this winter, we’ve had our little cold spells. The top question goes to Daphne this week: Why do plants freeze and what will return?

This annual Salvia coccinea is gone for good, unless it re-seeds in self-appointed locations!

frozen salvia coccinea

Microclimates, plant DNA, maturity, and temperature all make a difference. As we approach the last freeze date, I’ll cut back my Pride of Barbados in readiness for new growth.

Freeze damage Pride of Barbados

Here’s how Daphne explains what happens, per Dr. Jerry Parsons, retired Extension agent: “Fill a glass half-full with water and put it in your freezer. Take it out the next day, once it’s thoroughly frozen, and immediately place it under a warm stream of tap water and watch what happens.”

As Daphne says, I bet you’ve already got it: the glass will shatter. That’s what happens to plant cells as they thaw out when temperatures warm up. Some plants just lose their leaves, like this lantana.

Lantana freeze damage purple leaf

Others lose their lives, like this perennial salvia ‘Anthony Parker’.

Salvia 'Anthony Parker' freeze

But get this: just 8’ away in the same bed, this one was fine!

Salvia 'Anthony Parker'

Since vegetables contain lots of water, a simple cover on freezing nights usually does the trick. Check out my neighbor’s hoops to elevate her row cover. They’re just plain old PVC pipes, easy to bend, but she doctored them up with a bit of spray paint!

On tour, first-time gardener Ellie Hanlon teaches us a few things, too!

On her blog, Mostly Weeds, follow her step-by-step process from Day 1 to irrigation how-to, including her dual valve system and fertilizer. When she first set up her garden, Austin’s water restrictions required a variance (that she posted on her fence) for vegetables. With a flick of a valve, she could turn off the drip system to her flowers.

Pruning prep + Fruit trees + Rooftop gardens

Christmas lights are down, but my shrimp plants glow like holiday lights all day!
Red shrimp plant in winter with evergreen sumac

That brings up the top question right now: when do we clean up and cut back? Well, I’m not cutting back that beauty just yet. I’ll take the Felcos to it in March to restore its luscious figure. With our swings from hot to freeze, we don’t want to encourage new growth on potentially tender plants like this one. I’ve never lost one to super freeze, but new growth would be fried. Our lives can get stressed, but no reason to freak out our plants!

I did cut back my hardy pink skullcaps (Scutellaria suffrutescens) that were just too woody. They won’t mind as they hurry up to cover themselves anew.

cutting back pink skullcap
Same thing goes for Salvia greggii, even though some are trying to bloom. Do it anyway! Cutting them back several inches now will promote new growth and lots of flowers soon (since they bloom on new wood). If you let this go, you’ll end up with lots of woody branches and a disappointing view come May.

Saliva greggi cut back

My Copper Canyon daisy (Tagetes lemmonii) just hasn’t got this figured out yet!

Copper canyon daisy (Tagetes lemmonii)
It’s supposed to bloom in fall, but it wimped around since my garden missed all those rains. Although it’s drought tolerant, this one was only in its second season. I gave it some deep soakings and it popped back from death row. Now, I’ll let it bloom its little head off and cut it back several inches in a few weeks. I didn’t prune last winter and that was a mistake. Pruning = powerful pretty!

Another plant we can prune sooner than later is rock rose (Pavonia lasiopetala) that is a total mess if you don’t take a firm hand.

rock rose pavonia lasiopetala stamens
Now, most of us know this as a pretty-in-pink perennial subshrub. But viewer Laura has one that seeded out pure white!

White rock rose pavonia lasiopetala
Daphne explains how Laura ended up with this beauty, and how she can get more of them. In a nutshell, Daphne reports that white flowers are recessive in rock rose. But sometimes through pollination, genes cross in such a way that both parents contribute the recessive white-flowering gene, instead of the pink-flowering one. Cool, huh?!

If you’ve been hankering for your own fruit trees, grapes, or blackberries, energetic Jim Kamas, Texas AgriLife Extension fruit specialist, joins Tom this week.

Winter drought care trees & wildflowers|Edibles meet perennials

Happy New Year! Good wishes to you all that 2013 sprinkles us with abundant joy.

'Patrick' abutilon

Unless we get a few serious sprinkles from above, we need to water our wildflower rosettes, like bluebonnets. Thanks to Jean Warner for Daphne’s question this week! Like Jean, my bluebonnets are up, along with larkspur and weeds—so be careful out there when pulling.

bluebonnet rosette

If you make a mistake like I have “now and then,” quickly plug the keeper back in and water. Here are baby poppies, not native, but still so pretty and beloved by bees.

poppy seedlings

So, Jean wants to know if freeze will harm her healthy crop of bluebonnets. As Daphne reports, cold weather isn’t a concern for our native wildflowers that emerge in fall to hunker down as rosettes until the magic moment.

But lack of water certainly is. Annuals, like bluebonnets and many others, will wither away and never flower and seed for next year without moisture. And we certainly don’t want to miss pictures like this Flickr sequence, thanks to KLRU’s Sara Robertson and her baby’s first Texas 2012 spring!

Sebastian in the bluebonnets

Lack of water is the reason we’re losing valuable trees, too.

Cedar elm winter

Tom joins consulting arborist Don Gardner to explain why it happens and what we can do.

Find out how far out to water your trees for their age and size. KLRU graphic designer Mark Pedini crafted this to illustrate one of Don’s important points.

Tree roots Mark Pedini Central Texas Gardener

In drought, the absorbing roots get smaller and smaller until eventually the tree only has woody, anchoring roots. Those fine feeder roots are what we must water to keep the tree alive.

Check out Daphne’s explanation of woody roots and whether we can plant over them.

Meet Don in person for more tree care tips on January 26 at 2 p.m. at the Lady Bird Johnson Wildflower Center’s Tree Talk Winter Walk. This free event is from 9 a.m. -5 p.m.

Watch this great video from the Texas A&M Forest Service for more on watering your trees.

Not only do we need to water our fruit trees, now is the time to apply horticultural oil to fend off hibernating insects and their eggs. John Dromgoole explains how to help prevent pests like plum curculio and bacterial and fungal disease with proactive care. Oh, the first thing is to sanitize the garden—all year long—by removing old leaves and fruit from the ground.

Fruit tree insect and fungal prevention John Dromgoole

If you don’t have space for fruit trees, I just bet you have a spot to grow pretty edibles, like this ‘Joi Choi’ bok choy!

‘Joi Choi’ bok choy Daphne Richards

Daphne’s Pick of the Week is something you can pick and eat: winter edibles!  And no need to restrict them to an official vegetable bed. Tuck them in among your perennials, like these at the Travis County Texas AgriLife Extension demonstration beds in October.

Edibles and perennials Travis Texas AgriLife Extension

Whether you eat it or not, nutritious Swiss chard is a beauty among winter annuals. Many of mine didn’t weather summer’s heat, but this one never faltered.

Bright Lights Swiss chard

You can still plant winter edibles among your dormant perennials for a pop of delicious color. In fact, check out the Master Gardener’s free workshop  January 17 on how to plant and save seeds.

Daphne also suggests letting some plants bolt or go to seed for their structural addition and flowers. With fall’s warm weather, many of our crops bolted early this year, so go ahead and replant, like lettuce.

Molly O’Halloran shares this lettuce soup recipe (which she thickened with diced potatoes) to use lettuce that’s past its salad prime.

Here’s another reason to “try it at home.” Look at the size of this carrot grown by Nancy and Richard Simpson in their year-round organic vegetable garden!

Notable natives

Even though rain and sweet cool days perked things up, I know that fall is here when my self-seeded goldenrods start blooming. Soon, they’ll be clustered with butterflies, bees and little wasps.

goldenrod Central Texas
They’re already heading to the shrub/small tree Barbados cherry (Malpighia glabra) that rebounded from a brief summer break to flower yet again. Later, birds will hone in on the fruit to fatten up for winter.

Barbados cherry flowers
This one’s on the side of the house, formerly photinia-ville, joined by a white-blooming Cenizo ‘Silvarado Sage’, a hybrid of the native Texas sage (Leucophyllum frutescens). A non-native thryallis (Galphimia glauca) joins them to screen and shade the air conditioner.

Barbados cherry Cenizo silverado thryallis
Daphne’s Pick of the Week, native damianita (Chrysactinia Mexicana) is going great guns in the right conditions, which I don’t have. This one thrives in the hot curb strips at Mueller. It’s a deer resistant low-grower that blooms for months (attracting pollinators) as long as it has sunny, well-drained spots that don’t get a ton of water.

damianita
My native frostweed (Verbesina virginica) opened its first flowers, too, ready for the butterflies in frenzy feeding.

Frostweed flowers
Oh, I got that one and many of my natives at the Lady Bird Johnson Wildflower Center’s plant sales: this year on Oct. 13 & 14 (member preview Oct. 12). You can even click to get a printable list of available plants.

The LBJWC is where you can nab the drought-tough groundcover, golden groundsel (Packera obovata), hard to find in the trade. In summer, it’s a lush little filler in part shade.

The Wildflower sale is just one event during Native Texas Plant Week, Oct. 14 -20. Check out all the fabulous activities to Keep Austin Wild, including tours and workshops.

Someone you’ll meet at the LBJWC sale is E.E. “Mitch” Mitchamore from Hill Country Natives, who grows hard-to-find native plants in his home-based nursery. This week, he joins Tom to pick a few native trees to create a canopy for shade, understory, fruit and wildlife appeal.

Tom Spencer and "Mitch" Mitchamore, Hill Country Natives

One he details for us is Bigtooth maple. At a mature height of 15’ or so, it’s perfect for smaller gardens. At his nursery you can see planted specimens to get a true feel of what they’ll look like in a garden. I like how he’s used salvaged fencing to protect this young Bigtooth from browsing deer.

On tour, see how Jackie Davis restored a typical small lot to an abundant wildlife habitat. Instead of exotic, dying trees and dog-trampled earth, her Certified Backyard Habitat is in constant motion with birds and beneficial insects. She’s got cool tips for feeding birds, too! To jumpstart her hands-on education, she became a member of Travis Audubon, the Native Plant Society and the Austin Butterfly Forum.

Many thanks to Meredith O’Reilly, blogger and gardener at Great Stems, for connecting me with Jackie. Meredith joins us on November 3 with more great native plant understory selections!

Until next week, happy planting to one and all! Linda

Fall in love with autumn bulbs and grasses

Big day in my garden! The autumn daffodils (Sternbergia lutea) popped up reliably a year after planting.

Sternbergia lutea autumn daffodil
These small crocus-like plants, native to the Mediterranean, are cute companions for red oxblood lilies and spider lilies (Lycoris radiata).

Lycoris radiata spider lily and Sternberia lutea autumn daffodil
Last fall on CTG, Chris Wiesinger, author of Heirloom Bulbs for Today, introduced me to these beauties that will naturalize in my Blackland soil, even in part shade! I wasted no time ordering these hard-to-find bulbs online.

Mostly though, I get plants from local nurseries supplied by local/regional growers (or grown themselves), along with passalongs from friends.  My native Plumbago scandens has been in non-stop mode for months against evergreen Texas sedge (Carex texensis). The plumbago will die to the ground this winter but return even stronger next spring.

Plumbago scandens with Texas sedge
Mine came from the Lady Bird Johnson Wildflower Center sales—coming up again Oct. 13 & 14 (member’s preview Oct. 12). You can even join that day to beat the rush for superb natives, including ones that don’t often show up in nurseries.

These days, many nurseries do have native grasses like Lindheimer muhly (on the left) and deer muhly (on the right):  this spectacular duo in Anne Bellomy’s garden.

Lindheimer and deer muhly seed heads

Native grasses, in the fields and in our gardens, are both lovely and beneficial. Many send down deep roots, benefiting aeration, stabilizing the soil, and improving fertility—along with providing shelter and food for wildlife. And in fall, they are the ultimate drama queens! My Lindheimer was our favorite autumn standout until it got too much shade and withered away. Until I find a sunny spot, I’ll just enjoy Anne’s.

Lindheimer and deer muhly
This week, Tom meets with Shirley and Brian Loflin, who note that grasses once predominated the Hill Country and the Blackland prairie.

Tom Spencer Shirley Loflin Brian Loflin
Their book, Grasses of the Texas Hill Country, is a friendly hands-on guide to identify and learn about both cool and warm weather grasses in our fields and for our gardens. This popular book is currently in reprint, available for pre-order from Texas A&M University Press.

Grasses of the Texas Hill Country Brian and Shirley Loflin

Currently, it is available as a Google ebook, too.

Brian’s photography helps make it easier to identify the grasses that soon will be in show-off mode, like curly mesquite. This one’s part of  the Habiturf mix that includes buffalo grass and blue grama for a native lawn in sun.  By the way, the Habiturf trio is available at the Wildflower Center and online.

Projects! Reduce lawn makeover! Container vegetables!

Revival! As the rock roses (Pavonia lasiopetala) and Turk’s cap swing back into gear, my ideas hit revival mode, too.

Rock rose and turk's cap
Projects are finally in the works.  Last spring, we laid a sandstone path over a section of dead grass, but wanted time to think about what to do next.

Path project lawn reduce

We’ve decided to get more sandstone, but to reduce the heat factor, I’m leaving wide spaces to plant frogfruit (Phyla nodiflora). You can see how the first ones are already creeping over.

Last March, I set out a few 4” pots to soften our new work. They’ve taken off like crazy, unmindful of the unamended soil, heat, drought or the brief spurts of drenching rain.

frogfruit on path

I’ve been digging up grass since the day we moved in, since I want a garden full of wildlife. When 2010-2011 took a hard toll on lawns, I lost a lot of the rest, as did many gardeners.

This week on tour, see how Lana & Bob Beyer retrieved their garden with stunning new ideas!

Transition time for flowers and food

Valentine’s Day started early with my potted carnation!

'Silver Pink' carnation

I love everything about it: color, fragrance, blue-green foliage, long-lasting cut flowers. Drought tough. If anything, they hate too much water, and demand perfect drainage.  Two years ago when I got this ‘Silver Pink’, I added decomposed granite to loose potting soil and “mulched” it with a  light layer of the granite.  This would be lovely in a large container with agaves. Hmm, may have to try that!

Purple oxalis sent valentines, too!
purple oxalis flowers

I love purple, but especially I love plants that don’t need much of my time. Between Sunday’s sleet flurries, I got a shot of this trouble-free team, which includes splotchy Arum italicum, columbine and a few Gomphrena ‘Grapes’ to the left.

purple oxalis, Arum italicum,  columbine
The oxalis and arum quietly retreat underground in summer, returning in late fall. ‘Grapes’ usually goes dormant in winter. I’ll cut it back in a few weeks to encourage its lush little leaves until it pops its “grapes” next fall.

Thanks to rain and cooler weather, the lettuces I seeded a few weeks ago are coming in just fine. Upfront is heirloom ‘Speckles’, one of my favorites, not just because of its coloring!

Speckles lettuce Central Texas Gardener
Some cilantro and parsley thought about bolting, but I’ve headed them off for now.

Flat-leaf Italian parsley
After I took this picture, I cut that parsley at the base to bring in for dinner, and to encourage new stems before it bolts for good. Once upon a time,  I could keep this biennial around for two years, but recently, early hot weather does them in the first year for me, though a few did show back up this winter.

Snapdragons are finally in strut-mode. Leafy Swiss chard makes a nice backdrop, when it’s not coming in to dine, like in our Valentine’s night vegetarian stir fry.

Snapdragons with Swiss chard

In this transitional garden time, how do vegetable growers extend their cool weather crops and make way for summer’s plants?  This week, Tom meets with Paula and Glenn Foore from Springdale Farm for some insider tips, including their favorite tomatoes.

Tom Spencer with Paula and Glenn Foore, Springdale Farm
For years, the Foores have been in the landscaping business as Texas Trees & Landscaping (and still are!).  Eventually, Glenn decided to fulfill a dream for a small urban farm on their land in east Austin.

Some of our fruit trees are still showing signs of damage from last year’s freeze. Daphne answers Rachel Jackson’s question about her troubled loquats.

Loquat freeze damage Rachel Jackson
We consulted Texas AgriLife Extension fruit specialist Jim Kamas. Here’s what he says:

It’s almost undoubtedly cold injury.  Loquat is a relatively cold hardy sub-tropical, but last year the warm temperatures during the end of January caused a loss of hardiness in all plants.  The cold front that came through on the first of February caused a sudden drop in temperatures.  We went from 74° to 11° in about 22 hours.

Loquat damaged by freeze Rachel Jackson

Since this could certainly happen again this year, here’s Jim’s advice for our fruit trees:

Keep the plants well watered, but not saturated, over the winter.  The drought last winter greatly exacerbated the problem with cold injury.  Trees can indeed repair themselves, but don’t be surprised if limbs continue to collapse and bark sloughs off of the trunk.  Just keep the plants in as good of health as possible, remove dead wood, and hope for the best.

Kale is a super healthy, easy-to-grow winter green. Trisha shows off her favorite varieties, including Redbor, to put on your list for seeding next fall.

Somebody thinks it’s spring!

Old fashioned petunia

I treasure fragrant old-fashioned petunias for cascading perfume in my spring and summer patio containers. Warm winter days prompted an energetic splurge at the base of a potted sweet olive (Osmanthus fragrans). Since they’re hard to find, I cover them when temps dip below freezing, though an old tablecloth was fine when we briefly hit 27°.

In January, it’s more usual to see violas. I go back and forth on winter annuals, but can’t resist a few of these edible beauties.

Just a few weeks into winter, already spring’s given us a heads up. When ‘Country Girl’ mums wear out and I snip them to tidy rosettes, naturalizing bulbs will flower power hungry insects.

I don’t mind the wait for poppies and spuria irises, too, since I’m keen on winter foliage that anchors our attention until explosion day.

Thanks to rain, last year’s poppy and larkspur seeds returned from self-appointed spots among bearded iris and winecups.  For me, anticipation is half the fun!

Daphne explains how to grow cut-and-come again lettuce, like Travis County Master Gardener Sheryl Williams’ late fall harvest from her ever abundant garden.

Yard Fanatic's lettuce and tomatoes

Follow Sheryl’s vegetable gardens, projects, and lawn reduction on Yard Fanatic!

Depending on weather (always), we can keep on seeding through early March. I planted more two weeks ago and they’re coming up like mad. Lettuce is pretty cold hardy, but for safety, cover if we drop below 40°, especially if you have little ones coming up. Like every plant, variety and microclimates make a difference.

My friend Mary Wachsmann, who writes at Food Joy, and documents her nummy recipes with her camera, is loving heirloom butterhead ‘Speckles’ in balcony pots.  Lettuce is perfect for small spaces and containers!

Insects, like our dormant perennials, are timing their emergence to chomp on our fruit and shade trees. Daphne explains how to fend them off with horticultural (dormant) oil.

Daphne notes: “This is the time of year that we can spray horticultural oil on fruit trees, as a necessary preventative, or other trees that have had problems, to naturally control overwintering insects, especially in their egg, larvae and nymph stages. . . They can also control many fungal pathogens by blocking their access to tender plant tissues, where they can easily invade.”

But if you don’t get around to it, here’s this week’s success story! In fall 2010, friend Bob Harper sent us his red oak leaves that had been skeletonized by earlier insects.

Daphne noted that the pests were long gone, so the best thing to do was to keep the tree healthy. Recently, Bob’s neighbor Richard Alwine nabbed this shot of a pest-free, happy tree!

On tour, visit avid gardener Cecilia Neuhaus, who was ready to cut back on maintenance and water. In her new garden, she worked with Landscape Architect Tait Moring to capture the essence of Italy with low-maintenance patios and formal walkways that blend flowers and food, wildlife and soothing introspection, on her Lake Austin miniature “Grand Canal.”

What do you know? Flowers!! + Remarkable Trees w/Matt Turner

My, oh, my.

Oxblood lily and plumbago Central Texas

Three days after the rain, I came home to a surprise: flowers! I almost fell over.  Though my oxbloods, tucked into plumbago, have yet to fail me.

A week ago, the Salvia greggiis looked on their death bed. “Not so fast with that shovel, sister.”

Each day brings another renewal, like these rain lilies, Zephyranthes candida.

I only planted my Lemon yellow rosemallow (Hibiscus calyphyllus) in late spring. I have given it extra water attention, but not a lot. The flowers are diminutive after its summer labors to stay alive, but if it handles winter, I’ll be getting more!

And yahoo!  Guess who’s coming to dinner. . .for the next several months!  I hope that these are straggler daisy (horseherb) seeds, but I know the others are winter weeds.

Weed seedlings Central Texas Gardener
That strip of lawn between our carport and the neighbor’s house gets NO extra water. Last year, the horseherb made a beautiful lawn to replace the grass that went belly up. But it also gets the hot afternoon blast, and with no irrigation, even they went dormant this year.

Weeds and seeds are coming up everywhere. For gardeners, “weeds” are the ones we don’t want; “seeds” are the ones we do!  It’s all in the eyes of the beholder.

This year, we behold lots of dying trees. On CTG, Tom meets with Matt Turner, author of Remarkable Plants of Texas, for a look at some remarkable trees.

Tom Spencer and Matt Turner, Central Texas Gardener
Matt is the ultimate story-spinner with true tales of historical use, including why huisache made its way into French perfume, and how soapberry tree got its name as gentle laundry soap. One native of note is Texas persimmon (Diospyros texana), treasured for its lovely form and bark in garden design.

Its February flowers are fragrant enough to attract our attention, along with early bees. The Gray Hairstreak butterfly lays her eggs on the leaves to feed her hatching caterpillars. Later, wildlife dines on its fruits, as do we, but generally our palette enjoys them best when fully ripened.

Black walnut (Juglans nigra) is a large tree (50-75’) that does like moister soil.

It’s one of our finest carpentry hardwoods, so treasured that historically its native population has been exhausted for furniture and gunstocks.
This native tree is the larval plant favored by the Luna moth, Walnut moth and Walnut sphinx moth. Its nuts, high in omega-3, are considered the best tasting native nut second to pecans. Its leaves and hulls make a beautiful warm brown dye.

They’ve weathered the drought well, and invite you to come take a look at their Open Days tours this fall. Wandering through its various microclimates will excite you with all-weather designs tested for everything that weather throws our way!

Some plants didn’t make it through drought, but I bet your Heart-leaf/heartleaf skullcap (Scutellaria ovata) did.  This week, Daphne answers a great question from Chris Busse: hers went underground in the heat. Will they be back?

Heartleaf skullcap (Scutellaria ovata)
Yes, they will!  Daphne notes: “Heartleaf skullcap is one of the relatively few plants that go dormant in summer, instead of winter, thus defying our ingrained view of how plants behave in response to seasonal changes.  We’re quite accustomed to plants going dormant in the winter, but usually around here, if something dies back in the SUMMER, it actually IS dead.”  But this plant likes cold weather!

It hunkers down in heat (like most of us) to return when cooler days arrive. Like Chris, I got scared the first year I had them, but they’ve returned reliably every year (and she reports that she’s spotted hers!).

They spread from underground roots, so when mine pop back up, I plan to divide them to put under perennials that will go dormant in a few months.

Last weekend, I planted a new one and a tiny native Plumbago scandens in the bed that recently got “aerated” for a new sewer pipe.

The plumbago is the one with the white flower in back. It will freeze back, but by next summer will fill that muted sun spot. This winter, the heartleaf will cover the ground. When it goes dormant next June or so, the plumbago will be in full gear. (The little plant on the left is a Gulf penstemon I dug up for the sewer line fix and just replanted).

Daphne’s pick of the week is Bamboo muhly (Muhlenbergia dumosa). This feathery grass is a drought-tough choice for those areas of muted sun, like under Pam Penick’s trees.

Mine has done beautifully in the front bed that gets dappled shade and blasts of afternoon sun.

I got a scare when it browned in the extreme freeze of 2009/early 2010, but it was a youngster.

Come spring, it was back! I cut the canes to the ground and off it went!

Frozen bamboo muhly returns Central Texas Gardener
The 2011 freeze barely daunted it. For me, that’s part of the fascination of gardening:  traveling from year to year to see what works and what happens.

And it’s certainly given me a gift that usually eludes me: patience.  No matter what the tags or books or even CTG says, where do they work in our own soil and light, freeze, drought and flood?  I’ve learned that even a few feet can make a difference on what happens.  We’re scientists, all, in our own gardens.

Scientists and gardeners alike can tell you that our soil took a real beating this summer. On Backyard Basics, Merrideth Jiles fromThe Great Outdoors, explains how to rejuvenate it to pump up those microorganisms and in turn, your plants.
