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.

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.

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 just received JA`s and want to plant them but we are into the colder months , should i store them and if so how or should i put them in the soil and wait for them to come up ? i dont want to lose these ive been searching for them forever

I would store them in a pot filled with damp sand until spring. If you leave them out they will shrivel and if you plant them they may rot unless you have good drainage. Once established they are virtually indestructible and would survive most winters.

I planted a couple of JA's in spring and about 8 weeks ago they shot up with lovely yellow flowers. I cut these off fairly quickly hoping the growth would go back into the Tubers. I am guessing i could dig some up, but i would like to also move some of the tubers to another spot. Can i do this now or should i wait until the spring?

You could 'raid' a few now if you wanted to. They would be riper when the plants start to die back for the winter. Even though they are just about indestructible it would be better to transplant them in the winter when they are dormant.

I planted Jerusalem Artichoke in February. It is now April and the plants look healthy but have only reached about 1 mtr in height. They reached this height quite quickly but have not moved for about 4 weeks. Is this natural? Thank you.

There could be a number of reasons including; a dry spell, cooler weather, planted late in the season, etc. but if your plants are healthy I don't think you need worry.
