Alyssum’s tiny, fragrant flowers of white, pink, or purple attract beneficial insects and butterflies. Use these ground-hugging plants to edge beds, borders, or containers.
To start seeds indoors: Sow the seeds on the surface of the medium without covering them, about 6 to 8 weeks before the last frost date. Keep the soil temperature at 60° to 75°F. Germination should occur in 1 or 2 weeks. Transplant the seedlings outdoors around the last frost date.
