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.

Popped mine in poor soil about 3 inches deep in Nov (I read they don't like rich, amended soil). Haven't seen anything yet. Maybe sunchokes in zone 10b is a problem?

The planting guide here says they won't grow in your zone.

I have had a scratch and they are producing tubers, so they don't have to flower.

This is my first attempt at growing Jerusalem artichokes. I'm in a temperate zone and planted them in November. Only one plant has produced one flower! Will this be a problem?

I've grown these in large 50+ gallon size bags and they do very well, however the bags can dry out quickly. I've found it best to grow them in wicking barrels cut from the plastic 55 gallon drums. These are much easier to keep moisture to the tubers.

Hi All, Sunchokes or Jerusalem artichokes grow great in Edmonton Alberta. I grow them for the flowers in my flower beds at the back. They are a wonderful perennial veggie and in the colder zones, we are limited on or perennial edible plants.

Will Sunchokes die in extreme heat? Even with irrigation?

By the guide here in Tropical Australia (hottest weather) you plant in Autumn and grow into/in winter. Summer might be too hot.
