Arisaema thunbergii subsp. urashima (Japanese Cobra Lily)
You're either an Arisaema person or you're not. And quite frankly if you're not, we don't understand you! This spectacular relative of our native Jack-in-the-Pulpit sends up truly crazy, horseshoe like leaves to 15" tall with 10-15 leaflets. The deep burgundy colored flower is stunning in color but even more of a conversation piece is the flower hood that elongates into about a foot-long whip. One of the coolest flowers in the garden!
