Re: Tree/Shrub for summer dirth SE KY
I planted some Vitex Negundo seedlings several years ago. I didn't know how well those bushes/trees would do here in East TN, but they are mostly doing fine. They are flowering now (not much else is here at this time but I do see some honeysuckle) and attracting lots of native pollinators. I had seen natives on the vitex previously, but today I saw honeybees on them also. Currently the vitex receiving full sun are about 5-6 ft tall. Ones in partial sun are about half that size.
Given that, I suggest planting Vitex in full sun. My Vitex seeds came courtesy of a Beesource member (thanks Almondralf) but I see that Seedman offers Vitex seeds for sale:
Korean Bee Tree (Evodia danielli) is a popular bee plant at Beesource, and offered for sale by several members. Search should turn up multiple threads on this tree. I personally have not planted any of these.
