Dear Rob, I really don't see why Dracunculs should fail in Seattle. Although your climate is notorious for rainfall, simply planting in a raised bed, adding drainage (sand or gravel) should be ample. Of course it will do best in your hot dry spot and in a spot that does not collect moisture and in full sun. Here in more difficult conditions it does fine in dry or moister spots in full sun or half or more shade. SO: Raised Bed Added drainage materials Full Sun Plant where it does not collect water runoff Try again. Good luck Jim W -- Dr. James W. Waddick 8871 NW Brostrom Rd.
