Sweet Alyssum 'Clear Crystals White'
Lobularia maritima 'Clear Crystals White'
4-inch pot
 
A vigorous and free-flowering selection, Clear Crystals White sweet alyssum produces masses of pure white blooms that create a soft, cloud-like effect. The flowers are lightly fragrant and attract pollinators, while the plant’s spreading habit makes it ideal for edging, containers, and cascading over walls or baskets. Its clean, bright color pairs easily with nearly any planting combination.
 
This variety is known for its improved heat tolerance and stronger growth compared to older alyssum types, allowing it to continue blooming longer into the season. It performs best in well-drained soil and benefits from occasional trimming to encourage fresh growth and continued flowering. Ideal for cool to mild conditions, it often rebounds well after summer heat.
