Propagation

This section contains historical Plants For A Future notes marked noncommercial.

Seed - surface sow in spring in well-drained soil in a sunny position in a greenhouse. Do not allow the soil to dry out. Prick out the seedlings into individual pots when they are large enough to handle, and grow them on in the greenhouse for their first winter. Plant out in early summer of the following year. Division in spring or early summer. Very easy, larger divisions can be planted out direct into their permanent positions. We have found that it is better to pot up the smaller divisions and grow them on in light shade in a cold frame until they are well established before planting them out in late spring or early summer.

Cultivation

Prefers a fertile well-drained soil in a sunny position[2]. Established plants are drought tolerant[2]. A good plant for the flower border[5]. This species has pink to white flowers[2]. All members of this genus are said to have edible leaves, though those species that have yellow flowers can cause stomach upsets if they are eaten in quantity[4][6].
