Superstars, outside and for your Indoor Plant Decor

There’s a lot to be said for summer annuals.

'Fireworks' globe amaranth
I’ve always adored globe amaranths, but this ‘Fireworks’ in Lucinda Hutson’s garden sparked a new love affair. Beyond, Duranta pops in some wowza color, too.

Here’s why Daphne makes globe amaranth (Gomphrena globosa) her Pick of the Week: It’s a Texas Superstar, which means it’s been tested around the state for worthiness in our gardens. You can find them in many colors and sizes, even for containers.

They bloom all summer, standing up to searing heat and drought, as in Daphne’s own trials with new varieties in the infamous 2011 torture. But did you know they attract butterflies, too?  They’re so prolific that you can spare a few as long-lasting cut flowers that dry like a dream. Wonderful in a wreath!

Recently, on a mini vacation, I fulfilled a dream to visit Texas Superstar’s Brent Pemberton at the Texas A&M AgriLife Research and Extension Center at Overton.

I’ll have more about Superstar in a later post. For now, it was a thrill to stroll the greenhouses where trial seeds and plugs start out.

Isn’t this Calliope geranium a gem? I can’t wait to see if it makes Superstar status!

Once they’re ready, they head to the fields for the ultimate test of endurance and performance.

My garden is a perpetual test ground. One superstar for me is bamboo muhly (Muhlenbergia dumosa), a grass that surprised me this spring with its first delicate seed heads.

Gulf penstemon found its own test grounds in a bed of Texas sedge (Carex texensis). Both rate **** for me.

Salvia microphylla ‘La Trinidad Pink’ survives the test of just not quite enough sun. A little floppy sometimes, it’s doing fine in morning sun.  It could stand to have a gardener that prunes it more often, you know?

But, I’ll admit: I’m so not adventurous indoors. That’s about to change, thanks to Indoor Plant Décor, authored by friends Jenny Peterson and Kylee Baumle.

Kylee was holding down Ohio, so Jenny joins Tom to pep up your house and office to take the humdrum out of houseplants with THE design style book that connects to your muse, budget and imagination.

Tom Spencer & Jenny Peterson, Indoor Plant Decor

In their book, Kylee and Jenny include plant lists and DIY tips in friendly style that prompts “oh, I didn’t know this/I’ve got to try THAT” on every page. Every stunning chapter plugs a new spin into your imagination and creativity, inside.

Back outside, are you seeing this on your trees or other plants?

Before you freak out about horrendous disease or insects, Daphne has the answer: our bizarre late frost. In full disclosure, Daphne puts herself on the line. To pump up her young Monterrey oak, she admits that she fertilized a little too early.  Hey, raise your hands if you’ve done that too!

Normally, it would have been okay that her tree responded by putting out new leaves. EXCEPT. In her microclimate, it got cold enough to damage the new growth. Get her complete answer on how to tell the difference in temporary freeze damage or something evil. By the way, her tree recovered just fine, and so will yours.

So, have you just about had it with flies, fleas, fire ants, and plum curculios? John Dromgoole explains how to tackle them naturally underground with beneficial nematodes.

On tour, visit the diverse gardens at Mueller, the ultimate “testing ground” in its restoration of wildlife habitat over former runways and parking lots.

Thanks for stopping by! Until next week, reach for the stars, indoors and out. Linda

Fall aster and larkspur in spring Austin garden
I love it when cloudy days in spring fool the fall asters (and many autumn perennials) to bloom along with the larkspurs.

Even though we got a break this winter with rain and mild temperatures, the insects got a break too.  They’re just as thrilled as we are!  Really, every year in Texas is tough. If drought doesn’t get us, it’s too much rain, too much cold, or too many pests. That’s why I rely on my personal superstars to hang with me no matter what.

In the cat cove: Winecups on rainwater steroids climbed up to join the native Pavonia/rock rose (Pavonia lasiopetala) and larkspur.

Red Admiral butterflies fuel up for another busy day.

I think they wear out going between the coneflowers and the Rusty blackhaw viburnum (Viburnum rufidulum).

Note: this native shrub thickets like nuts!

My Angelica pachycarpa hangs out with me every winter until June or so. Now it’s sending up flowers before it crashes in a few weeks.

Underneath, I’ve planted White veined Dutchman’s pipe (Aristolochia fimbriata) to cover the space when it goes dormant. Since pipevine swallowtail butterflies are nectaring all over the garden, I suspect they’ll be laying eggs soon.

But did you know that there are official Texas Superstar plants, thanks to research at Texas A&M University? This week on CTG, Tom meets with A&M professor H. Brent Pemberton, Texas AgriLife Research, to commend a few that you can find in nurseries right now.

One is the Cora and Nirvana Vinca (periwinkle) series. These summer annuals are resistant to the aerial Phytophthora fungus that devastated our periwinkle chances in the past. They are tolerant of heat and humidity and DEER! In this picture, they’re in the foreground of other Superstar plants, like Esperanza.

Brent explains how Texas AgriLife Research trials plants under grueling Texas conditions to make sure they’re tough enough for your garden! Watch for this Grandma’s Yellow Rose rose, here with Burgundy Sun SuperSun Coleus and Tidal Wave™ petunias.

One I discovered last year in a garden is Angelonia angustifolia Serena ™series.

It’s a summer annual, but if you like that snapdragon/larkspur look in summer, it takes the heat, sun and drought! Just nabbed a few myself!

Here’s Brent’s CTG list. Plus, check out all the Texas Superstars. One to watch for is cenizo (Leucophyllum langmaniae ‘Lyaa’s Legacy’) that can bloom more often in summer than other selections.  But since all varieties of cenizo/Texas sage are superstars, it’s Daphne’s Pick of the Week!

Cenizo, Texas sage

But why do they fail for some of us? Daphne explains why. One is poor drainage, too much water, and not enough sun. Even a gutter that gushes into the area can be fatal.  The picture above represents a fatality in my garden when trees grew up and it didn’t get the hot blast of sun it really wanted.

The second reason is pruning it too much. Cenizo really doesn’t want to be hedged to perfection. Just lightly shape it to encourage more growth.

On tour, meet some superstar butterflies and birds at the Bulverde/Spring Branch Library. Thanks to the Comal County Master Gardeners and Friends of the Library, a rocky slope at the end of the parking lot is now an instructional guide to gardening and wildlife, plus an outdoor haven to read a book!

Daphne’s question of the week comes from Nettie Birnbaum: “Do we need to clean or sterilize our pots or black plastic 6-packs before replanting or seeding?”

Pots to be cleaned and sterilized before planting again

Yes! Daphne recommends cleaning with soap and water and then a 10% bleach solution. Rinse well and dry.

Since many of our container plants need to be divided this time of year, Trisha explains how to do that. She also shows how to separate new nursery plants, like basils that are overcrowded.  Get her tips on amending/sterilizing old potting soil, how to keep ants out of your pots, and how she starts summer crops in containers until winter plants finish for the year.

This Sunday, join the CTG team and the Travis Master Gardeners at KLRU’s 50th anniversary birthday party!  We’ll be making “eat a rainbow” bracelets for kids (vegetables!).  Plus there are tons of activities, PBS characters, and the Biscuit Brothers for this family fun day! It’s noon – 4 p.m. on 2nd street in Austin. See you there!

Thank you for your support of CTG as we head into KLRU’s 51st year! See you next week, Linda
