unusual shade plants
I'm interested in putting a few new, unusual or unexpected plants into my shade gardens, which vary from dappled with some sun to solid shade. Only 2 conditions: 1. no cactus, and 2. I don't have much space to bring out-of-zone varieties indoors for the winter, so I pretty much need to stay with whatever will be happy during the winter in zones 5 thru 6. Any suggestions? Anything out there that will shock the neighbors? Make friends turn green with envy?
Your thoughts, please.
