Nas, yes it is perinial and spreads slowly over the years so you are never without it. The recipe page says it is rather sweet and is very nice with recipes that will allow a lemon sauce to be used. I wil let you know again after we have had a few frosts.
I wrote awhile back about American Land Cress and may not have made myself clear. When it is ready to pick it almosrt exactly like water cress. It tastes exactly the same but it grows in the garden like a normal plant, whereas Water Cress needs to be in running water. I bought the seeds from Bournville Garden Center near to Cadburys in Selly Oak. I planted 2 seed per peat pot. I then planted the pots when the cress was about 2 inches tall. I have had to pull quite a few out and put them on the compost because it grows so fast. I defy anynone to tell the diference between this and water cress.
I have grown tumbler toms this year in hanging baskets. They were rather slow fruiting initially but for the last 2-3 weeks we are picking a few every day. they are small, hard and taste great.
