Here is a hardier version of the flowering maples listed earlier. I grew these shrubs from seed about six years ago. There are peppered about in the orchard bed, next to the house in the dog run, and in a pot on the back patio.
The flowers of these plants are gorgeous–large and silky, in small clusters at the end of branches. The leaves are handsome, as well. Like their more tender cousins, I have the toughest time growing these into handsome specimens. They have long internodes and long, whippy branches atop spindly trunks.
One of the seedlings has beautiful pure white flowers. They are slightly smaller than those of its lavender siblings, but they light up a dark corner next to the lilac bush in the dog run. I will work to add flowers here of that seedling.
