Sweet Alyssum (Lobularia)

Sweet Alyssum Plant Features

The honey-scented flowers of sweet alyssum make this easy-care annual a delightful addition to hanging baskets, containers, or border edges. It's a compact, trailing plant that grows just 6 to 10 inches tall and produces trusses of gorgeous blooms in shades of pink, white, lavender, or purple. Sweet alyssum is also highly attractive to butterflies and other pollinators. This rugged annual flower is also relatively cold hardy so you can use it in the early spring when the temperatures hover in the 40s and 50s.
