Will Sunchokes die in extreme heat? Even with irrigation?

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"

I live in Redland Bay Qld and I am finding it impossible to buy or find Jerusalem artichoke tubers. I so desperately want some to plant. Could you please help me find them. Sincerely Marlane Rogers

Hi I have been growing them for 20 years plus. Sell my excess on eBay And Gumtree. Sold 35kgs this year (and I eat/ate a lot myself! Lol) they are very productive and so easy to grow

There are currently several people and nurseries selling Jerusalem artichoke tubers on EBay Australia. I've just bought the cheapest lot from Sydney NSW.
