Prick out the seedlings when they are large enough to handle and grow on in a cold frame. Plant them out into their permanent positions in late spring of the following year. Cuttings of half-ripe wood, July/August in a frame[6]. Division in early spring or just before leaf-fall in the autumn[6].

Occasionally cultivated for its edible fruit, there are some named varieties[4]. 'Emerald Carpet' is an ornamental thornless form with orange berries that resemble small raspberries[4]. Plants in this genus are notably susceptible to honey fungus[6].
