  • 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 1.5 m 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.

We had our first crop of these last year. Really delicious - similar to potato but with a nutty flavour.

Cooking tip: These are unbelievably delicious eaten when mashed half half with potatos. I am sorry they don't grow up where I live.

These are very versatile.I make soup,saute,mash,boil them. I leave them in the ground in winter and dig up as I need them. Good if you have diabetes as has inulin (mimics insulin).

I love these and find the best way to cook them is unpeeled and they then peel easily, with fingers, while hot. Delicious - like a cross between an artichoke heart and a kipfler potato

VERY invasive, but we do have them here for sale in our community gardens

Have stacks of these and find they are a great substitute for bamboo shoots in a curry or stir fry. Peal, slice thinly and throw them in at the end so they stay a little crispy.

Please be careful giving advice re: diabetes. Inulin may sound like insulin, but it does NOT mimic insulin. Inulin is a type of oligosaccaride whereas insulin is a polypeptide; two entirely different classes of bichemical molecules.

I have found them to be almost embarasingly productive. One small root produces about 1kg of food for us.
