Propagation of the herb:

Seed - we have no information on this species but suggest sowing the seed in a cold frame as soon as it is ripe if possible. Sow stored seed in late winter in a cold frame. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Division in spring just before active growth commences, or in autumn. Larger divisions can be planted out direct into their permanent positions. We have found that it is best to pot up smaller divisions and grow them on in light shade in a greenhouse or cold frame until they are growing away well. Plant them out in the summer or the following spring. Cuttings of mature wood of the current seasons growth, 5 - 10 cm long, October in a cold frame. Roots quickly. High percentage.
