Growth—

A plant of the cool to cold temperate zone, where it is found at elevations up to 1,500 metres. It grows best in areas where annual daytime temperatures are within the range 15 - 34°c, but can tolerate 12 - 35°c[1]. When dormant, the plant can survive temperatures down to about -25°c, but young growth can be severely damaged at 0°c[1]. It prefers a mean annual rainfall in the range 400 - 1,000mm, but tolerates 300 - 1,100mm[1]. Requires a sunny position[2]. A plant of wet habitats, it succeeds in wet soils and in water up to 30cm deep[3, 4]. Prefers a pH in the range 5 - 8, tolerating 4.5 - 8.5[1]. A very ornamental plant[5]. The flowers have a scent of bitter almonds[6].

Propagation

Seed - best surface-sown in a cold frame as soon as it is ripe, it usually germinates in the spring. The seed quickly loses its vitality if it is not kept moist[2]. When large enough to handle, prick the seedlings out into individual pots and grow them on in a tray of water in the cold frame, planting them out into their permanent positions in early summer. Division in spring[7]. Very easy, larger clumps can be planted direct into their permanent positions. It is best to pot up smaller clumps and grow them on in a cold frame until they are well rooted before planting them out in the summer.
