Alyssum Planting and Care Guide
Quick Facts About Alyssum
Alyssum is a fast growing annual that forms a carpet of flowers. It has a sweet smell similar to honey that attracts bees, butterflies, hummingbirds, and other pollinators. Alyssum works well in pots or windowboxes or as a groundcover and has blooms in shades of white, pink, red, violet, yellow, and lilac.
Alyssum seeds can be directly planted in the flower bed in the spring once the soil has warmed and frosts are no longer expected. Or, start the flower seeds indoors 6 - 8 weeks prior to the end of frost season.
A sunny location is best for Alyssum plants, but some afternoon shade would be good for hot climates. The soil should drain well and be kept moderately moist.
