Plum to purplish-green leaves; bright yellow flowers through summer, followed by red berries. In cold winters, the top-growth may die back to the ground, with new growth emerging from the roots. Even if it doesn't, it's good to prune back hard in spring to encourage a flush of new colorful growth. Deer resistant.

Foliage goes to its full dark-purple coloration in fall

We left this plant behind in our Pennsylvania garden (and wish it well); we don't grow it in Houston.
