P = Plant tubers

  • 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
  • Jerusalem Artichoke/Sunchoke
  • 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.

I live in Redland Bay Qld and I am finding it impossible to buy or find Jerusalem artichoke tubers. I so desperately want some to plant. Could you please help me find them. Sincerely Marlane Rogers

I could send you some - but pretty sure that’s not possible / legal from Victoria into QLD?

Look up internet seed selling websites. Google - where to buy J A's.

Can I grow sunchokes in containers ? If so does it require anything special and when is the best time to plant?

Hello I've just been given a huge bag of Jerusalem artichokes. No problems in using them but I want to keep some tubers to plant out at then of winter /spring. Can anyone tell me how to store them until then.

Plant a few them out now. As sunflowers, they are prettier in a north facing spot. They'll be fine as long as they get a bit of water. Be warned they can be quite invasive over a couple of year period if you're not careful.

Do you think I could grow these in the Wairarapa? We have frosts to about -5 in winter.

I’ve seen them growing in a few Wairarapa gardens - not sure if people water them but I’ve also seen them growing along side the Ruamahanga under one of the bridges so I guess it should be fine!

Mike, you can leave the tubers in the ground in warmer areas of NZ, we have done that in Northland. In fact it is difficult to find all the tubers, so they will probably shoot up in the Spring even if you have light frosts.
