Family

Botanical Name

LOBULARIA maritima 'Snow Crystals'

Plant Common Name

Sweet Alyssum

General Description

The vigorous tetraploid cultivar 'Snow Crystals' becomes covered with showy clusters of fragrant pure-white flowers that are larger than those of other sweet alyssums.

Sweet alyssum is a low spreading herbaceous ornamental native to the Canary Islands and southern Europe. In the wild, plants behave as both annuals and short-lived perennials, but they are most commonly cultivated as annuals.

The low-growing mounded plants become covered with fine, light green foliage. They bear markedly fragrant, large showy clusters of tiny white flowers that cover plants for much of the growing season.

Sweet alyssum is drought tolerant and adapted to seaside conditions, so it does well in sandy or gravelly soils and full sun. Flowering diminishes and growth becomes lanky in hot weather — cut back plants if they become leggy. Popular as a bedding and container plant, sweet alyssum may also be used in rock gardens or along walkways where its strong, sweet fragrance may be enjoyed. It makes a good winter annual in regions with mild climates.
