where can I buy them

Helen, this site says "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. " - and I entirely agree !! I bought two small ones in Safeway (NSW) in November and planted them in a boring spot, no soil preparation at all. I got ZILLIONS of them - the soil simply heaved up and when I dug, there were beautiful JA's. Mind you, I use them sparingly in the kitchen because of the side effects lol. BUT, they are a handy addition for bulk to winter dishes and stirfries, now I can pop out into the garden and dig a couple up at any time. So watch and wait for your supermarket to have some for sale, after one season you will be self-sufficient ! Good Luck

Today I bought a net of JA tubers to plant at Bunnungs. $12 for 8. I asked about 8 weeks ago and they weren't avail. Are now, though! (23/7/11)

I got a lot from my grandfather one year but made the mistake of dishing them up to a group of friends just before we went to see a play..... those who have eaten them before can imagine the consequences. Really yummy, but unfortunately they do have a side effect not compatible with a quiet live theatre.

These are so so yummy! I scrub wash under running water, boil them in salted water, or steam them, they don't need a long time cooking, so do test before you strain them. I then chop finally continental parsley and garlic, sprinkle this over J A drizzle olive oil salt and pepper, and this is a great dish to have with canned tuna, olives etc etc..Oh...the gas comes free :)

what is the best way to store them?
17 May 12, Monica (Australia - cool/mountain climate)
Found this reference on another website: Tubers are difficult to store because of the thin skin which permits shrinkage and injury that leads to decay. They keep perfectly if left in the soil until needed, freezing does no damage. Although they cannot be harvested from frozen soil, tubers for spring planting are best left in place until spring. They should then be harvested and handled promptly before they sprout appreciably. Tubers should not be left in poorly drained soil. Good, sound, diseasefree tubers can be successfully kept several months in cold storage at a high humidity and a temperature of 0°C.

These are realy nice raw too. It is the first year I have grown them and they are so easy to grow with loving neglect!
