In the garden

Iberis sempervirens 'Snowflake' sits in the Brassicaceae and presents as a spreading branched evergreen ideal for forming low mats. It is suited to sunny, sheltered locations and is classed H5—hardy in UK gardens—so it will tolerate typical winter conditions when sited appropriately. Position this plant in full sun on soils that are moist but well-drained; acceptable soil types include chalk, loam and sand, and it prefers neutral to alkaline pH. A south- or west-facing aspect helps the plant establish and flower reliably. Shelter from strong, drying winds will protect the evergreen foliage and flowering display.

Its evergreen leaves provide structure outside the bloom period and the plant flowers in spring. Flowers appear April to June.
