I found some small, started plants at a garden sale that said Sunchokes. Hearing previously that these were tasty, I bought three plants and grew them in a small plot. I didn't do the best to care for them, because I didn't really do any research and I'm not an experienced gardener by any means, but they grew very tall and flowered regardless. Where I live, it has now frosted twice, and I thought I read that it was at this time that they should be harvested. I'm not sure if I should have waited longer. I got a fair amount of little tubers with the roots, but they are very small and do not look much like Google images. If I attach a photo of my "harvest," would someone be able to identify that these are indeed sunchokes and safe to eat?
Thank you so much for any help!
P.S. The image makes the plants appear a bit larger than they really are, I believe.
