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.

When should i see the flowers bloom. My sunchokes are growing very tall, look amazingly healthy, but no flowers yet on January 28.

Generally tubers do't form on plants like sunchokes and potatoes until after flowering. As with potatoes there will be some forming but they will be immature and not keep. Trust this helps.

my sunchokes are growing well in perth in improved bedding. question: Is it a good idea to remove lateral shoots from the main stem to improve growth?

I don't think it would make any difference as sunchokes are very tough and can be invasive if left. Any small tubers left in the ground will sprout next season. A lot of sunchokes I have seen are small and knobbly but some are plump and more rounded. If you get some nice rounded ones save them for next season and eat the small knobbly ones. Over a couple of seasons you will have all plump ones. Sunchokes are often called Jerusalem Artichokes. Trust this helps

Hi natcha nottle I grew Jerusalem Artichokes for the first time last season. They came up a treat with little to no extra care required! I'm in Newcastle NSW and grew them in a sandy soil but I gather they are quite hardy and tolerate a lot of different climates and soil types. I got my Jerusalem Artichokes from the Diggers Club They sent me three tubers which all came up when planted and produced a LOT more tubers which I am harvesting now. Hope that helps. JimboC

I'd like to plant sunroot in my garden. Do you supply people its seeds or root, or could you please tell me anyone who also plant it in WA? Thanks.
