alpine roscoea

Grow in humus-rich, moderately fertile, moist but well-drained soil. A cool, sheltered site in partial shade is ideal; in very cold areas apply a deep winter mulch. If growing from a tuber, plant 15cm deep

Remove faded flowers, the rest of the plant will die down naturally

Propagate by seed in pots in a cold frame as soon as seed is ripe. Propagate by division of tubers in spring when growth is starting

May be attacked by slugs and vine weevil

Generally disease free but a virus may be a problem
