Thank you for all of the messages.
To weedwhacker: they are definately butterfly bushes. Thanks for double checking with me. In fact I have 18 of them. White , blue , cran-raz, red, indigo, purple, royal. And two yellow ones being shipped. I am fascinated by them, love the smell, the attraction of butterfly's ,and they do well for me.
The ones I inquired about are in their 3rd season and last year they got to almost 12 feet tall. I just didn't remember the bottom being so "bare." But I gotta say, the tops are healthy and keep getting new shoots on them. I'm just trying to learn as much as possible about them. I get a little over- nervous when things don't look right!
Hope Yall have a super day!!
