Here in SW and NC Ohio we do have heat and drought at times, but not prolonged. I looked at the neutral and negative responses and think it must be the areas that are causing problems. The butterflies love them, too, and at times are covered with them. I love them! They bloom for a long time with minimal deadheading and, if pruned well, do not spread. I have 3 of these at my main home and one at the lake house.

The Royal Horticultural Society has given this cultivar its coveted Award of Garden Merit. It can reach 8-10' tall here even when cut back hard in early spring. In my observation, this is one of the tallest Buddleia davidii cultivars, and its flowers are the most deeply colored of any, a clear rich blue-violet.

A definite show stopper! In shade or on dark cloudy days the blooms appear black. My favorite butterfly bush! If you want a plant as tall as a tree with giant stunning blooms that explode with color every time the sunlight hits them and grow bigger and more numerous each successive season this is the one for you.

I forgot to prune my butterfly bush to the ground and what’s growing now looks pretty sad. It’s now mid June in hot, central Oklahoma.

They wilt really bad, the tips of the leaves are turning brown. I planted 3 of them where they would get a few hours of full sun. The information on the plant says to plant in full sun, but it seems to hate the full sun in Central Texas.
