Prick out the seedlings into individual pots when they are large enough to handle and grow them on in the greenhouse for their first year. Plant out in late spring or early summer. Division in spring. Fairly simple, if large divisions are used it is possible to plant them straight out into their permanent positions. Basal cuttings of young shoots in spring. Harvest the young shoots when they are about 10 – 15cm tall and pot them up in a lightly shaded position in a greenhouse.

Young leaves – raw or cooked. A strong anise-like fragrance, they are normally used as a flavouring or as an addition to the salad bowl. We find them a bit coarse and too strong for use as a salad. The leaves can be used as a tea substitute. A pleasant flavour. The seed is possibly edible. No further details. The seed certainly should not be poisonous, but it is very small and its use would be very fiddly.
