Cultivation Details

HabitPerennial
GrowthSlow

Requires a very well-drained gritty humus-rich deep soil in a sunny position[1, 2]. Prefers a neutral to acid soil[3]. This species is not reliably hardy in Britain[1]. It can withstand consistently very cold weather but does not like alternating periods of mild and cold conditions, nor does it like winter wet[1]. The plant is very susceptible to rotting at the neck in a damp soil[2]. Plants die down after flowering and start growing again in the autumn[3]. Very apt to hybridize with other members of this genus[1].

Propagation

Seed - best sown as soon as it is ripe in a cold frame in a very freely draining soil[4]. Sow stored seed as soon as possible in a cold frame. One months cold stratification should improve germination, though this is still likely to be very slow. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for at least their first two winters. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Division in early to mid spring. Very difficult.
