Well, of course you can keep it! But your question is... will it survive and do well? I have several crape myrtles in my yard and they sure are pretty but I'm in Arizona. The web says....
"Crape myrtles trees mostly do well in warm zones 7-10. Cultivars such as Dynamite Sioux, Delta, and Enduring Summer thrive in hardiness zones 7-10. Only a few cultivars can do well in the cold climates of zone 6. Pocomoke, Acoma, Caddo, and Tonto are some of the developed cultivars that thrive in cold temperatures."
I have bought some plants... a Cape honeysuckle and a Hammer's Rose come to mind, that are rated
for zones 8-11. They were both supposed to grow 6-8' tall. I'm in zone 8b.So I was on the cusp. Even though they survive here it is still too cold for them and they die down to the ground every winter and only grow to about 2' each year. Bummer! But the big box stores still keep selling them here. So I don't buy any plants now unless I am somewhere near the center of the hardiness zones. Hope this helps. Happy gardening.
