Name: josephine Arlington, Texas (Zone 8a) Hi Everybody!! Let us talk native.
I have them, and yes they spread, but no problem to take out unwanted shoots, lovely plant for pollinators and birds.
It is almost evergreen here in zone 8, likes moist soil, and does better with a little shade rather than full sun.
Wildflowers are the Smiles of Nature.
