Mary Sue discussed and set up a wiki page for Lysichiton, the "skunk cabbage" genus native to the Pacific Rim region in both Asia and North America. Lysichiton americanum, the yellow-flowered species, is native to my property in northwestern Oregon, growing in the bottom of a ravine with permanent springs. (Unhappily from my point of view, the native vegetation is so dominating that I can't even think of gardening there, however much visions of primulas may dance in my head.) The early spring flowers are indeed pretty, but you can smell them 100 meters away. When people have asked for a start of it, I hand them the shovel; dividing it is a demanding task. I don't recommend introducing it to the garden where it can't be confined, however attractive it is. Sorry, I have no photos -- how often we neglect to photograph the common plants native to our area! I've read that L. camschatcense, the white-flowered species found on both sides of the North Pacific, is less aggressive, and indeed it seems to be. I have it in a small artificial bog in the garden, where it has grown well and flowered for some years and has produced a seedling, which surprised me. It isn't foul-smelling; presumably it has different pollinators. Jane McGary Northwestern Oregon, USA
