Sweet Alyssum - White - Lobularia maritima - Light airy carpets of flowers - Fresh Seeds

White sweet alyssum (Lobularia maritima) is a simple way to refresh the look of a garden with soft, compact mounds of snowy white flowers. It forms low, neat cushions that catch the eye for months, and the tiny blooms release a gentle, honey-like scent that makes borders, pots and rock gardens feel especially welcoming. Easy to grow, tolerant of less-than-perfect conditions and generous in flower, it suits both experienced gardeners and those just getting started.

Sowing depth

Sow sweet alyssum seeds very shallowly, at about 0.3 cm deep. This helps seedlings emerge quickly and evenly. Cover the seeds with a thin layer of soil, press lightly, and keep the compost slightly moist. The first green seedlings should appear after only a few days.

Sowing time outdoors

The best time to sow directly into the ground is March or April, when the soil has warmed and the risk of frost is low. In good conditions, seeds germinate readily and soon form a dense green carpet that later becomes covered with white flowers. You can also sow in containers or window boxes to decorate a balcony or patio.

Spacing

Keep a spacing of 10 x 15 cm when planting out. This gives each plant room to spread and branch well, creating thick, cushion-like growth. Good spacing also improves air flow and helps reduce the risk of fungal problems. With the right care, sweet alyssum quickly becomes a bright, flowering carpet.

Flowering period

White sweet alyssum flowers from June through to October. This long season keeps beds looking lively for months, while the light fragrance helps draw in bees and butterflies. It works beautifully in borders, edging, containers and rock gardens, where it blends naturally with other summer-flowering plants.

Growing tips

Sweet alyssum grows best in sunny spots or light partial shade. It does not need rich soil, as long as the ground is light, free-draining and not overly wet. It tolerates dry conditions well and handles strong winds, making it a reliable choice for exposed places. Regularly trimming faded flowers encourages fresh growth and more blooms. It can also self-seed, so it often returns the following year and creates a natural-looking display.

White sweet alyssum is ideal if you want plenty of flowers without intensive care. Its clean white colour highlights other plants and brings a sense of lightness, freshness and elegance to the garden.
