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.
Gardenia jasminoides 'Frostproof' is an evergreen shrub for gardens in zones 7–10. It grows 3–4 ft tall and 2–3 ft wide, so plant it 2.5 ft apart. Give it full sun to part shade and average water. It flowers white in May to June. In a FloraVista list it usually plays the structure role: a shrub that holds the bed's shape at the back all year. 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 the Desert Southwest, the Mountain West and the Great Plains, where summer heat, humidity or mild winters hold it back even inside its zone range.
