Thanks for posting this Jeremy.
It looks like I've been under a misapprehension. Camas is one of the new world plants that I have been trying out growing here - they seem to grow pretty well. But for some reason I thought they were harvested in autumn along with silverweed, springbank clover and rice
root - all together. It seems a pity to harvest when in bloom, but it certainly makes finding them a lot easier! I wanted to try digging mine for the first time this autumn, but couldn't quite remember where they were, so have left them for another year. Maybe I'll try them this spring coming instead.
