Propagation

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

Seed - sow late winter in a greenhouse in a lime-free potting mix and only just cover the seed[12]. Stored seed might require a period of up to 3 months cold stratification[3]. Another report says that it is best to sow the seed in a greenhouse as soon as it is ripe[8]. Once they are about 5cm tall, prick the seedlings out into individual pots and grow them on in a lightly shaded position in the greenhouse for at least their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Cuttings of half-ripe wood, 5 - 8cm with a heel, August in a frame[12]. Slow and difficult. Layering in late summer or early autumn[12]. Another report says that spring is the best time to layer[8]. Takes 18 months[12]. Division of suckers in spring or early autumn[3].

Cultivation

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

Requires a moist but freely-draining lime free soil, preferring one that is rich in peat or a light loamy soil with added leaf-mould[2][8]. Prefers a very acid soil with a pH in the range of 4.5 to 6, plants soon become chlorotic when lime is present. Succeeds in full sun or light shade though it fruits better in a sunny position[8]. Requires shelter from strong winds[8]. Hardy to about -30°c[6]. A dense suckering low-growing shrub[5], it spreads rapidly when in a suitable position[8]. Very suitable for growing in the rock garden[2]. This species is closely related to V. deliciosum[2][5]. Dislikes root disturbance, plants are best grown in pots until being planted out in their permanent positions[8]. Plants in this genus are notably resistant to honey fungus[8].
