Our selection from near the extirpated location of a dwarf population above Carbonado relayed to us by NW plant legend Edith Dusek.  This has proved to be very atypical in that it produces a zillion crowns in a single plant,  A one gallon pot plant had 50 divisions, a large garden clump over a thousand.  Smaller than lowland clones.

White Skunk Cabbage.  Beautiful Asian version of our familiar Skunk Cabbage.  Big white flowers are a knockout and they don't smell bad - what a bonus!  Good rich moist soil or boggy spot.
