One plant when grown well produces the below quantity of edible tubers. You will get 5-10 times as much as you planted.
After one growing season select the best artichokes and plant them again.
Growing instructions, harvesting tips and recipes can be found here.
Plant the tubers into the ground or into large pots as soon as you receive them.
Choose a sunny position with well-aerated, free-draining soil. Jerusalem artichokes prefer evenly moist soil — they dislike both waterlogged and very dry conditions. Before planting, enrich the soil with plenty of good-quality compost. They especially thrive in rich homemade compost, but well-rotted manure such as sheep manure is also excellent.
On Banks Peninsula, we plant our tubers from late July to early August. Shoots usually emerge once the soil temperature warms to around 12°C.
Space tubers approximately 40cm apart in a diamond pattern. Plant them just below soil level and cover with a generous layer of organic mulch to help retain moisture and build healthy soil. Suitable mulches include:
Jerusalem artichokes grow into tall sunflower-like plants and reward minimal effort with a plentiful harvest of delicious tubers.
Here are more ideas for mulches in your garden.

Stachys affinis
The tubers have a distinct shape and look a bit like a grub. When eaten raw they are crisp and sweet like a water chestnut. When fried they are more starchy, soft and sweet, resembling a slightly nutty potato or kumara. In France they are known as crosnes and are typically served braised in herbs and butter, which is our preferred way to eat them. They are a great brain food.
Order is for a starter bag of about 5 tubers.
Growing instructions can be found below. Frost tolerant as they go dormant over winter.

Produces bunches of large red fruit with pointed ends.
