I just remembered another mission!
What: a regional variety of Northern Bugleweed, Lycopus uniflorus. A great deal of attention has been given to the Chinese Artichoke in
permaculture circles, it is an unusual edible tuber from the mint family. Less know are the edible tubers of Northern Bugleweed, the only other mint family
root vegetable I know of. I've never identified this plant, much less tasted it. But
native people used to eat it for desert- it must be good.
Where: Swampy places in Southern BC or Northern WA. Apperently it grows with cattails and other riparian vegetation.
When: I have no idea when the seed ripens. Presumably one could transplant tubers any time durring the dormant season.
