Also, is it ok to buy and plant now or is there a time when it is better? Thanks.
Barton Springs Nursery on Bee Cave Rd. usually has a nice selection. Any large nursery should have them. I would normally not plant anything this time of year, but they say to buy Crape Myrtles when they are in bloom so you can be sure of the color. Do your research because some get huge while others stay small.
They're everywhere, almost every local nursery should have them. Check out this website: www.clemson.edu/crepemyrtle/ and when you know what you want, shop around.
Normally this would be a bad time to plant, but we're getting so much rain (and no end in sight yet) that you might well get away with it, as long as you remember to keep watering once it gets really hot and the rains stop (assuming they ever do!) For larger specimens, do you know those "tree gator" watering bags....but be careful to not overwater crepe myrtles. Fall is actually the best time to plant trees and shrubs in our area, so you can also buy your crepe myrtles now and just water them in their pots through the summer.
A lot of times, in the fall, people sell them on the side of the road for about 10.00 - 15.00....they are usually 4 - 5 feet tall. And they are blooming so you can know what color they are.
That is a great time to get myrtles.
