Description Lobularia maritima Other Name sweet alyssum Sun Requirements Full sun, part sun Bloom Period and Seasonal Color Blooms all summer in colors of white, lavender or pink Mature Height x Spread 4 to 6 inches x 6 to 12 inches Added Benefits attracts butterflies, attracts beneficials, deer resistant Alyssum is a low growing annual that is known for its carpet of sweet smelling white, violet or purple colored flowers. It grows and flowers best during the coolest parts of the summer in New England, but in northern and coastal areas can be in flower all summer long. The narrow hairy leaves are inconspicuous when alyssum is in full flower. Bees, butterflies and other insects love alyssum making it a good plant in a pollinator garden. In my garden it will self-sow readily and become a permanent fixture each year. However, I still like to replant new varieties each spring for added color and to grow more vigorous plants.
