Lobularia White Knight

White Knight® II Sweet Alyssum

Fragrant, Heat-Tolerant White Blooms for Containers and Landscapes

Brighten your garden with White Knight® II (Lobularia hybrid), an award-winning annual prized for its large, fragrant clusters of white flowers that attract bees and butterflies all season. Unlike some sweet alyssum varieties, this heat-tolerant selection does not set seed, ensuring continuous blooms from spring until the first frost. Its compact, rounded growth habit makes it ideal for landscapes, hanging baskets, window boxes, and upright containers.

Compared to Snow Princess®, White Knight® II is smaller and more rounded with a less trailing habit, making it perfect for gardeners seeking neat, fragrant, and low-maintenance blooms that fill spaces with color and pollinator activity.
