Proven Winners® White Knight® Sweet Alyssum (Lobularia hybrid ‘White Knight®’)

Proven Winners® White Knight® Sweet Alyssum (Lobularia hybrid ‘White Knight®’) is a vigorous flowering annual prized for its masses of fragrant white blooms and exceptional heat tolerance. Unlike older alyssum varieties that slow down during hot weather, this improved hybrid continues flowering heavily throughout the summer season, making it an excellent choice for hanging baskets, patio containers, borders, and landscape edging.

The small clusters of bright white flowers create a soft cloud-like appearance while releasing a sweet honey fragrance that attracts bees, butterflies, and beneficial pollinators. Its naturally mounded to trailing growth habit allows it to spill beautifully over container edges and blend seamlessly with petunias, calibrachoa, and other colourful annuals. The fine-textured foliage remains tidy and attractive throughout the growing season.

In Alberta, White Knight® Sweet Alyssum performs best in full sun to partial shade with fertile, well-drained soil and consistent watering. It thrives during Prairie summers and provides reliable continuous flowering from spring until frost with minimal maintenance. Regular feeding helps maximize blooming performance and plant fullness.
