I'm not sure I totally understand but crapemyrtles are available in hundreds of cultivars from small bushy dwarf shrub forms up to 30' tall trees. So they will vary from one to another.

Seeing as how you're in houston, you will want to make sure that whatever crapemyrtle you select is proven to be cold hardy in your area. Ask your nursery where there are some mature ones around.

After examining the photo it looks like that particular one may have had had winter problems. Judging by the number of stems it looks as if stems have died and regrown new ones. This could explain the shorter height.

I also noticed the utility lines overhead. Be sure whatever you plant there will not grow too tall.

I agree with musicalperson's first post. Different crApe myrtle cultivars vary widely as to how fast and how large they grow. The smaller tree you mentioned may have been stunted by it's root containment, but other variables may also have contributed. Trees properly planted in decent ground should definitely have an advantage over those confined to a container.

Many cultivars also typically grow numerous trunks. I don't believe the presents of multiple trunks, by itself, means anything about winter problems or dieback. Many (most?) crApes will naturally form multiple trunks if not trained at a young age.

Thank you for the link. The picture I posted is not my tree. I just wanted to show the color of the flower.

oops: presents --> presence
