(Best months for planting Jerusalem Artichokes in Australia - sub-tropical regions)

P = Plant direct in garden where they are to grow.


  • 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 in same bed): 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 - Jerusalem Artichokes are a great promoter of flatulence in some individuals.

How can we store recently harvested tubers from now until planting time in Nov/Dec?

Easy to grow. I have success growing in Adelaide in clay soil. Only need a few tubers and you will have an abundance.

I've grown sunchokes successfully in Brisbane. They came up again the following year from pieces left in the garden. The secret is to make sure the soil is fairly dry (very well drained) over winter so they don't rot. If you live in the wet tropics I would suggest growing in a large tub or mounded to keep the tubers from getting waterlogged.

Its been 50 years since I grew Jerusalem Artichokes. But supermarkets and nurseries in Perth (Western Australia) look at me stupid when I ask about them Eastern States outlets are prohibited in sending them to WA. Is there anyone in the Perth Metro area that has these? I would like to beg, borrow, buy or steal at least one tuber to get me going again. In the past I grew them in the UK, they grew like weeds and can be hard to get rid of if not controlled. They grow just about anywere. A case of try them. If they grow, good, if not, bad.

Go to Swansea market on Swansea street Victoria Park. It's a left off Albany highway into Oats street then first right, if you're coming from the north. Anyway they sell Jerusalem Artichokes for food, don't know if they will sprout, but it may be worth a look if you're in the area.
