]. The plants will often sulk for several years if they are divided[
Leaves and young shoots - cooked. A famine food, it is only used when all else fails[
]. Some caution is advised, see the notes above on toxicity.
Seed - sow autumn or spring in a greenhouse. Prick out the seedlings into individual pots as soon as they are large enough to handle. Grow on for at least their first winter in a greenhouse and plant out into their permanent positions in spring after the last expected frosts.
Division with care in early spring or autumn.
