Jerusalem artichoke dilema

Well ive been looking for some jerusalem artichokes for some time - and on sunday whilst i was on at the local gardening shop someone brought in a tray of them - so i grabbed them

- the only problem is that ive never grown them before - so i dont know what to do with them, they are in a tray full of soil and have shoots on them around 3 inches high, im wanting to grow these in pots, so do i burry the tuber, foliage and them keep earthing them up like pots - or plant the tubers just below the surface so that the foliage is on the top.

Bought 3 from the fuit and veg section in As.a a while back.  My neighbour had them on his plot last year and the flowers were fantastic.  Mine are destined for the garden.  Growing really strongly now 

Jerusalem Artichokes? Ruddy weeds!

They ar'nt nick named Jerusalem Fartichokes without reason. We love em sliced and lightly fried in butter or a soup of them or mashed in with spuds. I agree with all above important to dig them all up at harvest time eat some save good smooth tubers in peat or sand in cool place over winter, plant 6 in deep in Feb/March depending on area. Can be useful as a shelter from prevailing winds as grow to 6/7 ft tall. Never had much in the way of flowers though.

My five tubers gave us plenty last autumn

I left a few small ones in the ground and now I have a thicket about 0.5 m by 1m 

Some have migrated into the path alongside the bed they are in too 

I do like the flowers, as they are very cheerful and a bit of a bonus on an edible crop
