Propagation

Seed - we have no information for this species but suggest sowing the seed as soon as it is ripe in a cold frame if possible. It is likely to require stratification before it germinates, so stored seed should be sown in a cold frame as early in the year as you receive it. Prick out the seedlings into individual pots when they are large enough to handle, and grow them on in a cold frame for their first winter. Plant them out in late spring or early summer of the following year.

Cuttings of half-ripe wood, July/August in a light sandy soil a frame. Cuttings of mature wood of the current seasons growth, 15cm long, October/November in an outdoor frame[2]. Another report says that September is a good time to do this[3].

Division of suckers in early spring[2]. They can be planted out straight into their permanent positions.

Cultivation

Tolerates most soils[2], but prefers a good loamy soil, abundant moisture and full sunlight[3][2]. Prefers a moist lime-free soil[4], plants quickly become chlorotic on chalk soils[2].

A very cold hardy plant, tolerating temperatures down to about -25°c[2]. Hybridizes freely with other members of this genus[3].

A rampant suckering shrub, it quickly produces dense thickets and can be used for large-scale naturalistic plantings[2]. It is apt to get thin and poor unless divided up fairly regularly and replanted in fairly good soil[5].
