Description
Roscoea alpina is a perennial herbaceous plant native to the Himalayas. In nature it grows in cold mountainous regions, and it is grown as an ornamental plant in gardens around the world.
In its native habitats, R. alpina flowers between May and August. Flowers open in succession and are purple or lilac in colour. R. alpina is grown in rock gardens. They generally require a relatively sunny position with moisture-retaining but well-drained soil.
The height reached in cultivation, up to 40 cm, exceeds that given for the species in the wild, where it is said to reach only 20 cm.
When grown at Royal Botanic Gardens, R. alpina requires more shade than other species of Roscoea.
Hardiness zones: 6-9
Seeds per pack: 3
Germination: Scratch each seed with sand-paper, or on a rough stone or brick, then soak in a warm location for 12-24 hours. Plant seeds just barely below the surface of the soil. If they have not germinated after 4 weeks then a cooling period is required. Cover them with plastic and place in a fridge for 4 weeks. Be sure they stay moist. After the cold-moist stratification period they are then brought back to 20C, 71F for them to germinate. Germination can be 30-60 days after the warming period, though some can take longer.
