  • Easy to grow. Plant tubers about 5cm (1.5") deep.. Best planted at soil temperatures between 46°F and 59°F. (Show °C/cm)
  • Space plants: 12 - 18 inches 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.

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.

If you go to website agric.wa.gov.au click on crops - under horticulture you will see vegetables - click on it. Click on Artichokes and then click on the heading - you will read all about how to grow them. I would try ringing/email the WA veggie growers association or similar and try and find out where to buy from. OR try and find a green grocer who might sell you some and post it to you. Or a friend or someone who lives in Perth. Try these sites - Australian City Farms and even Remote Indigenous Gardens network. Good luck.

Does anyone have any JAs at this time of the year? I'm looking for up to 15 kilos but any amount ok. Jan 2018

I live in wa and found some shriveled up chokes at my local iga. I planted them and thought they had died but eventually they popped up and grew. I planted out all the tubers the next year and kept expanding my crop.That was 3 years ago. This year I have planted close to 200 tubers and gave away many more. They grow well here, just need to keep them watered in summer and you will be rewarded. To store them I layer the chokes with coarse sand in a bucket with a lid and give them a spray of water if the sand gets really dry. I am happy to share them if you live in perth.

Hi Leanne. Thank you very much for your information. What would be the best time to plant them in Perth. Can you give me some tubes? - Chi

I have grown Jerusalem artichokes - sunchokes - for two years. What got left in the ground last Fall grew in the late Spring. After two days of below zero temperatures this week I harvested more than 20kg of tubers from about 15 plants. From reading articles and from growing them I learned I cannot find all the tubers when I dig in the Fall. They must be harvested in the Fall, no tubers will form until day length is less than night length.

Where can I buy them in the Sandton, Fourways area? Thanks

Not sure if you have come right yet, but if not... Jerusalem artichokes will probably not be on sale until the end of the season - at the moment they are putting all the energy into the flower and won't be of a quality to sell. You can keep an eye on www.seedsforafrica.co.za and www.theseedvault.co.za, both of these sites usually have tubers available when in season.

Can tubers be planted in the fall and harvested the next summer like I do with garlic. We usually have a late spring so it's hard to plant until at least June.

Jerusalem Artichokes can definitely planted in the fall. Studies show that fall plantings are, in fact, better for production as it promotes an earlier start for the plant.
