REDBUD VS CRAPES . . . NO GRASS UNDER TREES?
This lecture title --
"Is Redbud the Next Crape Myrtle?" -- totally intrigued me. This is Dr. Dennis Werner's June 8 presentation at Pineywoods Native Plant Center in Nacogdoches.
Our native redbuds (Cercis canadensis var. texensis) are gorgeous spring-blooming trees or shrubs, easily spotted in woods all over this area. Eastern redbud (Cercis canadensis) is, in fact, native throughout Central and North America.
And they've long been a focus for Dr. Werner, one of our nation's truly outstanding horticulturists, and a major research study at North Carolina State University. Was this a prediction? And/or a fun title to draw attention? If so, it sure worked!
I love "back stories." This catchy quip, it turns out, literally leaped out of a lively conversation between Dr. Werner and our own acclaimed Texas horticulturist Dr. David Creech, Stephen F. Austin State University Professor Emeritus and director of the SFA Gardens in Nacogdoches, home of the Pineywoods Native Plant Center where Dr. Werner will be speaking.
News of the proliferation of new redbud releases sparked the quip: "Is redbud the next crape myrtle?" Both agreed this teaser title would definitely draw the eye, given how popular crape myrtles are in home landscapes. Even if it's a bit of a stretch, it's hard to beat redbuds for spring sparkle.
THURS., JUNE 8: IS REDBUD THE NEXT CRAPE MYRTLE by DR. DENNIS WERNER, 7pm, Ina Brundrett Conservation Education Building, Pineywoods Native Plant Center, 2900 Raguet St., Nacogdoches. 936-468-4404 or firstname.lastname@example.org
In his presentation, Dr. Werner will explore the genus Cercis, progress made in 20 years of redbud breeding at NC State, and new trial selections. If you ask me, the perfect combination is to have both one of the new redbuds for spring color and some great crape myrtles for fabulous color the rest of the growing season!
FIRST, THOUGH, READER FEEDBACK:
- Helen Mooty, Galveston County historian extraordinaire had a gardening question after last week's advice on leaving an open collar around tree trunks:
I have removed planters surrounding my 40-year-old oak trees and am trying to get grass to grow around them (it won't). So now I know I can put in an "open collar" a foot wide and be OK!
My added response:
Nothing is worth losing that oak. And nothing will make grass grow in the shady area under a tree.
Option: Put mulch under the tree. Insert pots of ivies, impatiens, wedelia, frog fruit . . . one of multiple choices available. Best to use just one or two of a wide variety. That way, you can always buy more of those you like and, even more important, that like you!
Improve their chances by slicing off the pot bottoms. Set on ground around tree. Pile enough leaves/pine needles up to hide pot so it looks like they're planted under there. The roots will co-mingle if you're patient.
Roots will (hopefully) grow downward slowly so don't compete with, or are killed off by, tree roots. Gradually new growth should spill out over the pot tops, setting new roots as it spreads. Keep well watered if it doesn't rain until you see new growth.
- DON DUBOIS responded to our caution about introducing potentially invasive "alien" plants into our area. He recommends the web site; plants.usda.gov, a USDA-funded interactive site.
AND NOW . . . ON TO REDBUDS VS. CRAPES!

IS REDBUD THE NEXT CRAPE MYRTLE?
By DENNIS WERNER
Dept. of Horticutural Science, North Carolina State University
There are certainly many shared similarities between crape myrtle and redbud as it relates to the available genetic diversity that can be exploited in a breeding program, and the subsequent combinations of attributes and characters that can be combined in new cultivars.
For example, as regards leaf color variation, in crape myrtle there is of course green, purple more recently, and a gold leaf variant just described in China about 2 years ago. Similarly, green, gold, and purple are now found in redbuds.
Flower color diversity in crape myrtle is remarkable. But redbud is competitive in that arena also, with white, pink blush, purple, pink, reddish/purple, and magenta.
Although there is a compact form of redbud in commerce ('Ace of Hearts'), the dwarf forms of crape myrtle are much more diminutive as compared to standard types, so crape myrtle dwarf forms are much more dramatic and distinct than are redbud compact forms.
Cercis canadensis 'Rising Sun,' Cercis 'Merlot' (tree and leaves) and Cercis 'Ruby Falls' (tree and leaves)
The major reasons that redbud will not be the next crape myrtle, if we use overall popularity and tree numbers sold as the criteria are:
1. Redbud is a spring flowering species, has a limited flowering time of about 2 weeks, and competes with scores of other spring flowering plants for market share. Crape myrtle, by virtue of its extended flowering in summer, has a unique niche with fewer flowering-tree competitors.
2. Redbud is typically a relatively short-lived tree, perhaps 20-30 years at best. Crape myrtle much longer in most cases.
3. Crape myrtle is much more broadly adaptable to various soil conditions and landscape settings. It can be grown successfully in less than ideal landscape settings (the strip between a sidewalk and highway) that rebuds often perform poorly in.
4. Redbuds do not tolerate winter injury, weed/turf competition, physical injury (weedeaters, lawn mowers) as well as crape myrtle. Although redbuds are more cold hardy, winter injury recovery is poor if a tree is damaged.
5. And lastly, the term "crape murder" has much more flair than "cercis murder"!!!!
Redbud has a few advantages, but they are for the most part minor.
1. The primary species marketed in the U.S., Cercis canadensis is native. Certainly very important to many people.
2. The flowers are edible.
3. Redbud is an important species as a nectar source for our early spring pollinators (butterflies, bumblebees, blueberry bees, carpenter bees, and other early pollinator species).
Whether in the wild or in the garden, Ceris Applachia Red is a winner!

The other day a customer stated that they had finished reading the new book "Teaming with Fungi" and were fascinated in how important fungi were as related to growing healthy plants. Hence, I was asked if there was a book where they could learn more. As it so happened, I recently finished reading a new and revised textbook on fungi that was far more detailed that I ever imagined a few weeks ago.
"The Fungal Community - Its Organization and Role in the Ecosystem",
4th Edition, John Dighton and James F. White, Editors, CRC Press, 2017, 597 pages, ISBN-13:978-1-4987-0665-0 (hardback)
This book is not for everyone but for professionals, serious gardeners, and students of the soil. It is 39 chapters each on a different aspect of fungi, the different species and what they do, how they grow, how they affect soil and plant growth. Having just been released this book is very up to date on all we know as a society about fungi and how important they are to our survival.
News from the wonderful world of soil and plants
Since I am in the middle of a series on minerals, and what they do for soil, microbes, plants and animals, many readers might find this interesting.
here was an article in the April 1, 2017 issue of Science News on Climate Change and Nutrition from the Annual Review of Public Health in January and Proceedings of the National Academy of Sciences. Studies are showing that as the climate warms trace elements like selenium (Se), iron (Fe) and zinc (Zn) will not be held in the soil, and plants will absorb less of these minerals into our food supply. These nutrients are already deficient in most of the foods that are being grown worldwide and the deficiencies are predicted to get worse. Note: Soils with a high clay content and abundant organic matter do a better job of holding on to these nutrients.
Most plants use what is known as the "C4" pathway for carbon capture. Researchers looked 41 species of cultivated crops and as carbon dioxide (CO2) levels rise nutrient absorption decreased. Over 2 billion people around the world are already zinc deficient and even a small change can drive hundreds of millions more people into deficiency.
The Intergovernmental Panel on Climate Change (2014) reports that crop yields are also likely to decrease as carbon dioxide (CO2) increases.
A multi year study by the United Nations with dozens of scientists from all over the world has found that due to the reasons above, the declining nutrient density of our food, and many other reasons, the only way to feed our growing populations is to convert all of the worlds agriculture to sustainable organic methods.
