About Alyssum
Sweet Alyssum (Lobularia maritima) is a low-growing cool-season annual for Northeast Florida, planted in fall and blooming with dense clusters of honey-scented white, lavender, or pink flowers from late fall through spring. Its spreading, carpet-like habit makes it ideal for edging, rock gardens, and mixed containers; plant in October once temperatures cool and expect blooms until late spring heat triggers decline. Starting at $6.95.

Care essentials
Light
Plant Sweet Alyssum in full sun to partial shade; in Northeast Florida it is used as a cool-season annual planted October through January, thriving in the mild winter sun when summer crops are done.
Water
Water regularly to keep soil evenly moist; Sweet Alyssum performs best with consistent moisture in well-drained soil. In Florida's dry spring months, weekly watering prevents wilting and prolongs the bloom season.
Soil & Fertilizer
Grows well in sandy, well-drained Florida soils with minimal amendment. Apply a balanced fertilizer at planting and once mid-season to extend bloom; choose heat-tolerant cultivars such as Snow Princess or Easy Breezy for best performance through Florida's warm spring.
