Feeding wildlife; Pond Society tour; periwinkle rot

I love free plants.

Bird seed sunflower with bee

These sunflowers sprouted from bird seed. I have no luck at all with the gorgeous hybrids, but without doing a thing, I get a wall of sunflowers all summer for bees and birds.

We’re loving watching the lesser goldfinches’ acrobatics on the zexmenias and the purple coneflowers. Not when I have the camera, of course.

Maybe I’ll be lucky enough to get a shot of hummingbirds and butterflies on the Dicliptera suberecta, since they certainly zoom in on this perennial.

Dicliptera suberecta (hummingbird plant)
The Diclipteras took a hard hit the past few winters, but decided to stick around. Actually, I rather appreciated nature’s editing, since they can get a bit out of control. But I love that soft gray, velvety foliage even when they’re not blooming. Mine get blasts of harsh sun, but not for hours at a time. In my semi-shady beds, they add the tall silvery tone I crave.

In the same part sun/part shade bed, bouncing bet (Saponaria officinalis) mingles with the lamb’s ears. I’ve also seen it growing like crazy in full sun. This sprawling, crawling perennial softens summer’s heat with sweet pale flowers.

Bouncing bet with 'Helen von Stein' lambs ears
Its common name, soapwort, derives from the saponin in its roots. Crush the leaves and mix with water for homegrown soap. I squished a few leaves in my grubby hands, applied the water hose, and lathered up a storm. Next time, maybe I’ll add some mint to my “yard bath.” As Cheryl from Conscious Gardening says, “Neato!” Yep.

Right now, water is the most refreshing sound and sight to both us and our desperate wildlife. If you’ve been thinking about a pond, fountain, or waterfall, immerse yourself in ideas on this year’s Austin Pond Society tour.

Anna Lisa & Rick Austin Pond Society tour
This week on CTG, Tom meets with Terrie and Michael Lumsden from the Austin Pond Society for a preview of just a few of the many gardens on June 11 and 12. And you can’t beat the price for passionate friendly hands-on advice from the gardeners. $15 in advance at selected nurseries, and $20 on site. The funds benefit their care of many public gardens.

Michael & Terrie Austin Pond Society tour
At each garden, pick up techie info (like liners, pumps, filters), design concepts, plant tips, advice about fish, and the “Oh wow”
magic we all need.

And, for the small ticket price, travel to a romantic paradise at Barbara and David Hale’s, CTG’s garden on tour.

In their basic backyard, one weekend at a time, they pulled from Pond Society tours, their travels, and their imaginations to change a muddy, shady backyard and humdrum front into a daily vacation.

A few weeks ago, I couldn’t resist adding some old-fashioned periwinkles (annual vincas), reminiscent of my childhood, against ‘Helen von Stein’ lamb’s ears, verbena, Agave striata, and ‘Hot Lips’ salvia.

With this year’s exceptional heat and high winds, I must water them every few days, until they’re ready to launch on their own (generally, they’re not water hogs at all).  But planting too early ends up like this photo from Lisa Maddox.

Periwinkle (annual vinca) rot
We thank Lisa for her great Daphne’s Question of the Week, since this happens to so many of us. Shoot, I haven’t planted periwinkles for years after I made the same mistake, since I’d heard that the disease never leaves the soil. And I learned my lesson on caladiums too! Nurseries entice us with periwinkles, caladiums, impatiens, and other heat lovers too soon. Yes, it may seem hot to us in April, but as Daphne tells us: the soil and nights are still too cool.

Diseases like Pythium or Phytopthora set in. As Daphne says, “These are both soil-borne diseases known as water-molds.  These diseases have spores that are motile in water, and in the spring rain or by watering your plants from above, you can actually splash those spores onto your plant from the soil.”

The disease will remain in the soil, but you can plant again! Just wait until the temps are reliably in the 80s next May. And make sure you mulch around them to prevent the soil  mold spores from splashing onto the leaves. This applies to tomatoes, roses and other susceptible plants, too. Thanks, Lisa, for helping us all out here!

John Dromgoole explains how to use anti-transpirants like Wilt-Pruf, Cloud Cover and Vacation to help new plants get established. You can even spray your Christmas tree with Wilt-Pruf and Cloud Cover to keep its needles fresh longer. Vacation is the one to use on houseplants (and outdoor plants) when you spring out of here for two weeks!

Until next week, Linda

    Linda, the question I answered this week on my blog was a periwinkle one also. Found out the folks at A&M have solved the fungal problem. Or at least found another way around it. http://gardendishes.wordpress.com/

    Thanks, Cherie!

    With these extreme temperatures, drought and high winds, are there any weather tolerant flowers that can be planted now? My back yard has no shade and the thermometer out there hits 104 regularly. Even my toughest drought tolerant plants are struggling with frequent waterings.


    Linda reply on June 2nd, 2011 7:17 pm:

    Robert, I’d hold off on any planting right now. Even the toughest can’t withstand this heat, drought and wind. Right now, we just have to plan, make our lists, and plant in fall!

    I do best with birdseed too. Somehow the others don’t come up…pillbugs?

    Great Dromgoule segment. We need all the help we can get in this drought. Denny and I are working on putting in our first drip irrigation segment. Why didn’t I think of this before it was 100F every day?

    Thanks for the tip about Wimberley Pie Company. Awesome coconut pie, one of my favorites.

    I’m thinking ants eat them. Or birds!
