I love perennials with huge foliage. Unfortunately, there are not many of them that are reliably hardy to my area. This is one family that does.
Rheum ‘Ace of Hearts’
This one was a disappointment. The leaves are small and unimpressive. It didn’t even attempt to survive its first season.
Rheum palmatum ‘Atrosanguineum’
This is currently my best Rheum in the garden. I am in constant fear that it wants to leave any time.
Rheum palmatum var. tanguticum
I believe this one is still around somewhere.
