Notes: Sweet alyssum is a charming, low-growing plant known for its delicate clusters of tiny, fragrant flowers in shades of white, pink, lavender, and purple. It is often used as a ground cover in borders, rock gardens, or hanging baskets. The plant thrives in cooler weather, making it an excellent choice for spring and fall gardens. Regular deadheading or trimming promotes continuous blooming and prevents legginess. Sweet alyssum is easy to grow from seed and can self-sow in the right conditions, providing blooms year after year in suitable climates. Its sweet fragrance and versatility make it a favorite for ornamental and functional garden designs.
