About Sweet Alyssum
Lobularia maritima is a fast-growing annual in the Brassicaceae family. It reaches around 10 cm tall and 30 cm wide at maturity, with evergreen foliage. White, purple and pink flowers appear for much of the year.
Where to grow Sweet Alyssum
Sweet Alyssum suits warm-temperate, Mediterranean and subtropical climates and grows best in full sun and part shade or morning sun. It is frost hardy and shrugs off cold winters. It also tolerates salt-laden coastal winds and is a genuinely water-wise choice.
Soil & planting
Most soils suit Sweet Alyssum provided drainage is reasonable. Plant into well-prepared ground, firm the soil around the roots and water deeply to settle it in.
Watering & feeding
Sweet Alyssum performs well with relatively little water once established. Apply a balanced fertiliser in spring to support healthy growth. New plantings need closer moisture checks in hot or windy weather, with watering tapered once strong new growth appears.
Pruning & care
Prune Sweet Alyssum after flowering to keep it compact and encourage the next flush of blooms. Its ongoing care level is low maintenance.
Using Sweet Alyssum in the garden
