(Best months for growing Jerusalem Artichokes in Australia - cool/mountain regions)

P = Plant tubers

  • Easy to grow. Plant tubers about 5cm (1.5") deep.. Best planted at soil temperatures between 8°C and 15°C. (Show °F/in)
  • Space plants: 30 - 45 cm apart
  • Harvest in 15-20 weeks.
  • Compatible with (can grow beside): Tomatoes, cucumbers
  • Artichoke harvest

These are the edible root of a sunflower. Plant the tubers deep enough to cover with soil. They are quite drought-tolerant, but keep well-watered to grow larger tubers. They grow through the summer to 1.5m-tall sunflowers with a smallish flower. Dig up the tubers when the flowers die down in autumn.

Get a couple of tubers from the supermarket or fruit shop. Two years after planting you will probably have enough to give away. Perennial, if you don't manage to harvest all the tubers - they will regrow year after year.

Culinary hints - cooking and eating Jerusalem Artichokes

Scrape clean or peel (add a tsp of lemon or vinegar to the water to stop the tubers browning). Steam, boil, or use in artichoke soup (make with artichokes and some stock). Caution - because they contain 'resistent starch' Jerusalem Artichokes are a great promoter of flatulence in some individuals.

Look on the internet.

I originally took free tubers left by a neighbour on the kerb. I planted five in a raised garden bed of one metre diameter. I've harvested about 5 kg of them! I've been giving them away, cooking & eating them, frozen the last batch as well. I call them fartichokes. They're a handsome plant with pretty flowers that don't appear until late summer.

can an artichoke be broken or cut into several pieces to be able to plant more?

Google growing them and go to the green harvest website.

Good afternoon, I've read contradicting info that jerusalem artichokes will and won't grow in the tropics. Can you tell me definitely which is right please. I have tried once to grow them in Townsville with no success at all. Are there guidelines for getting good results in the tropics or are they just not suited to the climate. Thank you Jan

I have a couple of month old one that I got for 10c at Bunnings. From what I have read, they really struggle with the heat during summer. I can attest to the fact that they hate water logged soil. Both of these sound like deal breakers in the tropics. I get the impression they would be the perfect plant for cooler temperate areas. If you are really keen, maybe you could try a single one in a large pot in a shaded and covered area and see if it survives the summer. At least you could reduce soil temperature and the amount of water it gets this way. I assume planting now and getting it established before it hits summer would also help.

It indicates here that artichokes don't grow in the tropics. There is probably a reason/s why - too wet - too hot. If you look at sub tropical it says plant Aug to Oct. That would be the best time to plant. You will never know until you try it.

Where can I get Jerusalem Artichokes in WA? I live on the edge of the desert and don't get to Perth very often. I have only seen them once in WA. I bought those and they grew well. We had a few meals out of the pot I grew them in, but unfortunately my wife threw away the ones I was keeping for the next year's crop. I have found suppliers in the eastern states but they can't supply to WA because of the quarantine restrictions.
