Bulbous, flowering plants, most suitable for cultiva-tion in the rock garden. Plant in autumn in a light, ordinary soil with an addition of sand. Set the bulbs 4 in. deep and 1 in. apart, in a sunny, well-drained position. After planting, cover the tips with old coconut fibre refuse, as a protection from severe frosts. Leave this protection until after they have flowered, when it should be removed in order to allow the bulbs to ripen. Lift and replant the second or third year after planting.
Increase by offsets removed at planting time and treated as old bulbs. Also seeds may be sown in cold frames in early autumn.
Puschkinia libanotica is closely allied to Scilla. It has opal-blue flowers, which last for quite a long time. It is excellent for the rockery, while it can be grown effectively in the border.
