By the guide here in Tropical Australia (hottest weather) you plant in Autumn and grow into/in winter. Summer might be too hot.

There's a yellow flowering bush that looks like Jerusalem Artichoke that grows wild around northern rivers- Uki NSW Australia that seems similar but flower looks a bit bigger & grows quite tall & I think the leaves are wider with a different shape, not ovste like the Sunchoke. Does anyone know if these plants that can run rampant are from the same family as the Jerusalem Artichoke?

Probably Tithonia Diversifolia or "mexican sunflower"

When do you plant and harvest Jerusalem artichokes in the winter rainfall areas of South Africa?

Go to the blue tab (climate zone) at the top of the page and work out your climate zone. Then go to J A and the info will be there.

I purchased some tubers from the green grocer and instead of cooking them I waited until tiny shoots appeared and planted them. Huge success with each tuber providing well over a kilo.
