Dracunculus vulgaris in Seattle Area

Dracunculus vulgaris probably does enjoy good drainage, but it grew
for many years in a poorly drained spot in my garden in the Cascade
foothills (annual rainfall 50+ inches) where it also got runoff from
a paved area. It does better, and flowers regularly (not necessarily
a plus unless you can tolerate the smell of carrion) in a sunny
raised bed. I saw it in the wild in considerable shade on old
terraces in very rocky soil. I see no reason why it should not
succeed in Seattle if given just a slightly elevated position.
