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
  • 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.

In answer to those seeking advice about where to buy Jerusalem artichokes in Cape Town: I bought some Jerusalem artichokes at the Vineyard Deli, Kenridge, chopped them into small pieces and planted them in a large wooden container. The plants are now (October) about 50 cm high and not flowering yet, but looking extremely green and sturdy.

I also found Jerusalem Artichoke plants at Ferndale Nurseries in Constantia, Cape Town!

I originally took free tubers left by a neighbour on the kerb. I planted five in a raised garden bed of one metre diameter. I've harvested about 5 kg of them! I've been giving them away, cooking & eating them, frozen the last batch as well. I call them fartichokes. They're a handsome plant with pretty flowers that don't appear until late summer.

can an artichoke be broken or cut into several pieces to be able to plant more?

Google growing them and go to the green harvest website.
