This plant is a new (this summer) acquisition. I love the plumes of blooms and am told it will be winter hardy here. Justicia ~ Brazilian Plume flower or pinecone geranium.

Although the hardiness is only down to 8a, it is said to be root hardy to zone 7b when mulched. It rebounds quickly from the root ball in the spring if your location has a heavy freeze.

Justicia ~ Brazilian Plume flower it blooms freely all summer.
