This is embarrassing but I just noticed this hedy blooming, there are dead flower panicles so it has bloomed before and I missed them. It was hidden in a jungle of Mutabilis rose, wax myrtle and a bunch of other stuff, I didn't even know it was in there. You know you have too many plants when you find surprises like this. I do not remember buying it, does anyone have an idea of which variety it might be?
