clematis 'Lunar Lass'

In mild areas, grow outside in a rock garden or over low shrubs in a sheltered position in full sun, in moisture-retentive but well-drained soil; in frost-prone areas, grow in an alpine house, conservatory, or cool greenhouse in full light, in soil-based compost such as John Innes No. 2; plant the crown at soil level, and keep the base of the plant and the roots cool and shaded by other plants or a layer of pebbles or flat stones; for more advice, see clematis cultivation

Propagate by internodal leaf-bud semi-ripe cuttings taken from spring to late summer, or by layering from late winter to spring

May be affected by aphids, capsid bug, caterpillars, and glasshouse red spider mite; flowers may be damaged by earwigs; young shoots are vulnerable to slugs and snails; container-grown plants may be affected by vine weevils

May be affected by clematis wilt, powdery mildews, fungal leaf spots, and virus diseases; pruned stems may be affected by clematis slime flux
