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 got some from a community garden. I've never tired them before. I broke them into smaller bits, washed them in water and fried them in garlic and butter. They are ok, ever so slight nutty flavour. In future I will use them to bulk up stews and soups. I have some growing as well. they are very tall, yellow daisy flowers and easy to pull up. I like them. They grow well in Adelaide.
