This diminutive alyssum thrives in full sun and moderate moisture, yet handles drought once established, making it equally at home in containers, borders, or between pavers. The flowers attract pollinators throughout its long season and remain undamaged by frost, extending color well into fall. Deer leave it untouched, and its tidy 4-inch height means no staking or heavy pruning required.
Paletta Mix Sweet Alyssum excels as an edging plant, cascading over the fronts of raised beds or containers where its low, spreading form can be fully appreciated. The continuous blooms also attract bees and other pollinators throughout the growing season, making it valuable for supporting garden biodiversity.
