Dave - Thanks for answering my questions.
I am going today to purchase another one, but will split the two in the pot I currently have. I think the other pots also had two. I might wind up with 4 plants if they all survive. That would be cool!!!
I really do like this ebony series of crape myrtles! They really are stunning plants with that dark foliage! Really unusual. Hopefully I can successfully get them to grow into tree form. That may be tricky if we have a cold Winter which might kill the trunk and branches to the ground. I've had that happen before with previous crapes.
