Lobularia maritima

The showy, white flowers of Sweet Alyssum provide spring blooms from April through June. There are many cultivars that offer a palate of colors to choose from. To encourage a second bloom, shear spent flowers from the first bloom. Blooms can be so profuse, they sometimes hide the foliage!

Find a protected area in your yard for these fagrant beauties, as they are somewhat intolerant of heat and humidity. Part-shade is preferred, but they can tolerate full sun. Try using Sweet Alyssum in containers for your patio, at the edge of borders around your yard, on cascading walls, and in rock gardens. Sweet Alyssum is native to the Mediterranean, and is commonly associated with sandy beaches and coastal landscapes.

Helichrysum petiolare

Licorice-plant is grown for its silvery, fuzzy-textured foliage and trailing habit. Its foliage may have a slight licorice-like scent.
