Name: josephine Arlington, Texas (Zone 8a) Hi Everybody!! Let us talk native.
The wood of Flame Acanthus doesn't die to the ground here but it might in Oklahoma.
I think it would be at least root hardy where you live, it sure is a beautiful and reliable shrub.
It does seed itself sometimes but not very often.
Wildflowers are the Smiles of Nature.
