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
  • 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.

Can I plant the chokes I just received in pots in my small, uheated greenhouse or should I hold them for Spring? If I should hold them, how do I do that?

Hi I bought some Jerusalem Artichoke tubers on trade-me a few months back and they have been dormant in the ground since about June. I am in Auckland, and the spot they are in is sheltered and sunny. NOTHING has come up yet. Should I worry?

Try checking here before planting anything. You planted early winter instead early spring. This is what happens when people plant out of season. If you had a wet winter they may be rotten. Dig around the tubers to see how they are.
