Where can i buy a few tubers of jerusalem artichoces, some for eating and some for planting in the northern freestate.

Hi Henk, Livingseeds carry them. Their site shows it as out of stock for most of the year and usually show available stock in early winter.

Popped mine in poor soil about 3 inches deep in Nov (I read they don't like rich, amended soil). Haven't seen anything yet. Maybe sunchokes in zone 10b is a problem?

The planting guide here says they won't grow in your zone.

I have had a scratch and they are producing tubers, so they don't have to flower.

This is my first attempt at growing Jerusalem artichokes. I'm in a temperate zone and planted them in November. Only one plant has produced one flower! Will this be a problem?
