Rodgersia podophylla, you had me at "great shade plant."
The kid and I went blueberry picking today and on the way home we stopped at Leach Botanical Garden. I don't buy things impulsively, but this plant was definitely an impulse purchase. At least it only cost me 12 noodles. It should get 5' tall and 6' wide, which is perfect because I have about 50' of fence that I don't want to see anymore.
