Planting and Growing Malcolmia

Grows very quickly from seed. Ideal as a quick gap filler between newly planted perennials and shrubs. Also useful as a container or edging plant.

Taking Care of Malcolmia

Water well in dry weather.


Pull up and discard plants on the compost heap, at end of growing season.

Pests and Diseases

Susceptible to attack by slugs and flea beetles. Can be affected by a downy mildew.

Propagating Malcolmia

Make successional sowings outdoors in a prepared bed, border or container. They dislike root disturbance so sow them where they are to flower. Sow from March onwards to ensure a long flowering season. For example: sow in spring for summer flowering, in summer for late summer flowering and in the autumn for the next spring. Thinning is not normally necessary. Self-sown seedlings often occur.
