Lobularia hybrid - Sweet Allysum

Lobularia blooms are dainty, clusters of tiny flowers, larger than those of cool-season alyssum and have a sweet honey fragrance. Deadheading, removal of flowers, is not necessary. They are fantastic on their own or in mix planting, keeping in mind their slightly aggressive nature give them plenty of room. Height: 4-6" Spread:12-18"

You might want to trim after flowering to keep the mound shape and encourage more flowers. The flowers attract butterflies.
