Half hardy. Perennial. These tubers cannot withstand freezing conditions or sitting in water. It is best to start the tubers in pots first, pot size needs to be around 4 ltr. Place the pots either in the greenhouse or somewhere that is frost free. Once growing and free from cold weather then plant out into the garden. If you have well-drained soil, plant them deep and cover in the winter with a mulch. Feed well throughout the growing season with a slow release fertiliser. If your soil is heavy it is best to lift the tubers at first frost, cut the stems back leaving an inch. Store upside down in a frost free environment, replant in April.
Propagation: Divide the tubers every couple of years.
