I've been growing ColorFlash astible for about 5 years and I love how the foliage changes with the seasons. however, mine never have blossoms that are as red as the one pictured. They're usually pale pink and don't make much of a statement compared to the leaves.

This beauty is dainty with a delicate bloom. Grows well in part shade with Hostas. It's only requirement is that you water it when the weather gets hot & dry.
