This evergreen perennial is covered with white flowers April to May. It is used as an edging between turf and flower borders very effectively, as it is only 6-10 in. tall. Grow candytuft in well-drained soil, full sun and water twice-a-week. Shear off flowers after bloom to keep foliage dense and encourage another blossom set.
