S. 'Purple Volcano'
After Googling this plant, I found out it's lyrata 'Purple Volcano', however, I found images of the same plants when searching for 'Purple Knockout'. Any known reason why the names have changed or why one plant shares 2 names?
My mom was thinking 'Knockout' might not have been very politically correct, hence the name change. Geez! LOL
Not much info on S. lyrata in general, either. Any culture advice for a northern Californian?
