Lobularia maritima (syn. Alyssum maritimum, common name sweet alyssum or sweet Alison), also commonly referred to as just alyssum (from the genus Alyssum in which it was formerly classified) is a species of low-growing flowering plant in the family Brassicaceae.
Lobularia maritima is cultivated in gardens, with many horticultural varieties with purple or pink flowers. The plant is best planted in early spring, but requires little maintenance when growing. Although an annual, it may re-seed in temperate climates. It will flower more profusely if spent blooms are trimmed. When grown in gardens, it is typically used as groundcover, as it rarely grows higher than 20 cm. It is also grown in cracks in paving and walls, and is especially associated with coastal locations. It prefers partial shade, and is resistant to heat and drought. Plants with darker-coloured flowers do better in cooler temperatures.
