    I love this peony! The foliage is distinctive, and the bloom is a lovely deep red. It gets bigger and blooms more every year (like any peony, I suppose). I appreciate that it shoots up earlier than other herbaceous peonies, so it's less likely to be stepped on by small feet when the kids are picking daffodils.
