Naniwa Nishiki - crimson, Bn
Online descriptions of this bright crimson cultivar are sparse, but at least one gives it as a semi-double. Such an attribution would suggest that the blooms contain multiple rows of broad petals that emerge from a crown in which pollen-bearing anthers are a prominent feature. You can judge for yourself whether the bloom shown here qualifies. Ascribing flower forms to peonies is somewhat subjective.

What a beautiful red! I didn't realize that peonies could be red, maybe its what you said earlier that the Tree Peonies come in a broader range of colors. I just love the structures of them, and the arrangement of those ruffled petals are wonderful and so beautiful.
