I live in the South Cariboo. I have been asking where to get Jerusalem Artichokes, many of my friends are interested in getting Jerusalem Artichokes, but no one seems to know where to get them. Is there easy access to buying them?

I grew this plant from seed and planted them a few years ago. They grew very tall but did not flower yet and there are no tubers at all. Any suggestions on why there are no tubers to harvest after at least 2 years in the ground. Thanks for your help. Lynn

I wondered the same thing about two months ago when I got some. I saw it starting to dry out so planted in pot with top showing to observe. Root never looked back and with sun on it is clearly photosynthesizing and just waiting for warmer weather to burst forth.
