Description
Alyssum (Lobularia maritima), often called Sweet Alyssum, is a classic edging and groundcover plant beloved for its clouds of dainty, honey-scented blooms that appear from spring through autumn. Belonging to the Brassicaceae (mustard) family, its small cross-shaped flowers reveal its kinship with cabbages and rocket. Alyssum’s compact mounding habit makes it perfect for borders, rockeries, pathways, and container gardens, where it spills gently over edges and fills gaps between larger plants. Flowers in white, cream, buttery yellow, pink and purple.
Beyond its ornamental appeal, Alyssum plays an important ecological role in the garden: its nectar-rich blooms are magnets for bees, hoverflies, and other beneficial insects, helping to support natural pest control and overall pollination. The flowers themselves are edible, with a mild, sweet flavour and subtle mustardy undertone—best used sparingly as a garnish for salads, cocktails, or baked goods.
Alyssum is very easy to grow from seed, quick to flower, and often self-seeds, ensuring ongoing displays in the right conditions. While it is technically an annual, in mild New Zealand climates it can persist or reseed year after year. Hardy to light frosts and tolerant of poor soils, Alyssum thrives best in sunny spots with free-draining soil, where it will spread cheerfully to create a carpet of blooms.
