Iberis sempervirens Snowflake

Snowflake Candytuft

Iberis sempervirens ‘Snowflake’ is a compact evergreen perennial valued for its abundant bright white flower clusters that cover the plant in spring. This candytuft forms a dense low mound of narrow dark green foliage that remains attractive through winter, with flowers often nearly obscuring the foliage during peak bloom. Its clean white bloom makes it a classic early-season edging plant.
