A magnificent low-growing, wide-spreading hardy annual producing a continuous display of colourful mixed flowers all summer long. Always early to bloom, Alyssum 'Carpet of Snow' has a ground hugging habit that is perfect for rock gardens or cascading from crevices in walls. With a toughness that belies its delicate appearance, sweet alyssum is surprisingly wind tolerant and makes a useful plant in coastal areas. Height: 10cm (4"). Spread: 25cm (10").
