I've grown these in large 50+ gallon size bags and they do very well, however the bags can dry out quickly. I've found it best to grow them in wicking barrels cut from the plastic 55 gallon drums. These are much easier to keep moisture to the tubers.

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.

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"
