Evergreen candytuft 'Purity'
Iberis sempervirens 'Purity'
Preview: plant data is awaiting horticulturist review. A professional horticulturist hasn't reviewed our plant table yet. Lists still follow fixed rules for zone, sun, pets, deer and invasive status.
Iberis sempervirens 'Purity' is an evergreen groundcover for gardens in zones 3–8. It grows 0.5–1 ft tall and 1–1.5 ft wide, so plant it 1.25 ft apart. Give it full sun to part sun and average water. It flowers white in April to May. In a FloraVista list it usually plays the edge role: a low plant that finishes the front edge. Deer may browse it when other food is short, and it is toxic to dogs and cats. Our rules leave it out of lists in Florida and the Gulf and the Desert Southwest, where summer heat, humidity or mild winters hold it back even inside its zone range.
