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

It took a while but I have learned to love Sunchokes. Undoubtedly the easiest and most prolific vegetable of them all. But what to do with them ? Boil them, roast them, grate them into salads, slice them into stir fry. I use them mainly as a filler. They thicken soups and stews and I mash them up with my spuds. Very economical. they don’t have a long shelf life (which is why they are ridiculously expensive) so I tend to leave them in the ground until I use them. If you have a lot of sunchokes - and you will - you can be brutal when you peel them. But keep the peelings out of the compost or you’ll end up with sunchokes everywhere ! Warning : They can be ‘noisy’. Not recommended for date night or before attending the cinema.

My Jerusalem Artichokes had very few tubers. Almost nothing. The soil is semi-sea sand in a winter rainfall area. The colour of the soil is like sea sand. What can I add specifically for Artichokes?

Hi All, Sunchokes or Jerusalem artichokes grow great in Edmonton Alberta. I grow them for the flowers in my flower beds at the back. They are a wonderful perennial veggie and in the colder zones, we are limited on or perennial edible plants.
