Crape-Myrtles in Southern Landscaping

Updated on February 25, 2017

My grandpa loved gardening. I learned much from him. To this day I enjoy puttering around in our garden growing plants for beauty & food.

Shrubs and Trees

One of the most beautiful of summer blooming shrubs and trees in southern landscapes is the Crape Myrtle.

The official name of this eye-catching plant is Lagerstroemia.

The crape myrtle can be grown as a bushy shrub or as a tree all depending upon how it is pruned and trimmed. New draping varieties can even be displayed in hanging baskets.

The height of the various forms of crape myrtle varies from about 18 inches to over 40 feet.

Color variations and shades of the different varieties can range from white to pink to lavender to purple and even red.

Climate Requirements

The plants thrive in hot and sunny climates so are generally seen in Zone 6 and below in the United States.

There are, however, newer and hardier varieties that can grow in colder climes.

The Lagerstroemias are native to India, Australia and southwest Asia.

Their very showy blooming period lasts from 60 to 120 days and adds so much in the way of grandeur to yards, parks and esplanades when the right time of year arrives.....that being summertime here in the south.

The blooming period can actually be extended if the spent flowering heads are pruned off. As the flowers develop on the new growth each year, this allows for another flower head to develop in time to re-flower.

Pruning and trimming crape myrtles correctly

We used to have two crape myrtles in the front of our yard at our old house years ago. They grew fairly rapidly as most plants do in the south and produced gorgeous flowers.

One problem we had with them and why we ultimately removed them was the constant battle we had with powdery mildew, leaf spot and black sooty mold.

All of these things can occur on crape myrtles and I have now discovered how this could have been better handled.

At the time, I took leaf samples into a nursery and all that they told me to do was spray with fungicide every week or two until the problem was resolved.

Now.......long after the fact.......I have learned that our plants were not pruned properly to allow much needed air flow through the branches which could have kept the problem from developing in the first place, or, at least minimized it.

There is a good video and link describing how proper pruning can not only alleviate fungal problems from developing, but can also create a much more pleasing appearance to the crape myrtle plants as they grow into wonderful specimens of great beauty.

Be sure and watch the video if you are considering planting crape myrtles in your yard or garden.

Crape Myrtle Varieties

The other thing that has happened over the course of years is that hardier disease resistant varieties have been developed.

So do some homework before you purchase crape myrtles and you will be rewarded by years of flowering splendor for many months of each year.

The bark of the crape myrtles keeps shedding and peeling off and what eventually results is a white-like hard stalk that is smooth and is alluring in its own right.

One neighbor that used to live near my mother at her former house was cutting down a couple of crape myrtle trees but was saving the attractive pieces of stalks (branches) to be utilized as drapery rods. They would have provided not only support for the curtains or drapes but would have been focal points of beauty all by themselves.

What a clever use of these eye-catching hard wood branches!

The photos in this post show just a few of the many brilliantly blooming crape myrtles in our neighborhood today.

When my family moved from Wisconsin to Texas many years ago, we heard someone refer to crape myrtles as the "lilacs of the south."

They do have a similar shaped flower head but do not have the fragrance of lilacs.

If you think of crepe paper and then look at a crape myrtle blossom, you will understand how it got that name. Very delicate ruffled and thin petals make up a crape myrtle flower.

Landscapes all over the south are graced this time of year with the varicolored crape myrtles in a heyday of peak color. Few blooming shrubs or trees offer so much coloration for so long a time. As the heat sizzles, the crape myrtles are at their sublime best.

      Hi Donna,

      I loved climbing trees when I was young. Nice that you got to climb a large crape myrtle in your grandfather's yard when you were a young girl. If not trimmed back, they can get to be very large specimens.

      Hi Rebecca,

      We don't have them at our current home either but all we have to do is look directly across the street to see them. There are many in our and businesses...just like where you live.

      Hi Mary,

      We do have lots of crape myrtles here in Houston despite the heat. We are now experiencing temps in the upper 90's and should hit 100 this Sunday. It feels much hotter than that. Any more serious yard work will have to be on hold until Fall temps arrive. Enjoy that AC in Florida. I know we are certainly enjoying it here! Thank hurricanes this year yet to knock out power. We could use some rain however. We are currently in a hot and dry spell.

      I love them! I remember one in my grandfather's yard big enough to climb when I was a little girl.

      Hi Au fait,

      We had pretty much the same situation here. Too much rain was probably the cause I am guessing. Our official high will be 100 this Sunday if the predictions are correct. We are now regularly hitting 97 to 98 with feel like temps much we are about the same temperature wise. Not sure you have as much humidity as we do but is HOT! Thanks for the share.
