Upright rosemary 'Tuscan Blue'

Salvia rosmarinus 'Tuscan Blue'

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.

Salvia rosmarinus 'Tuscan Blue' is a fast-growing evergreen shrub for gardens in zones 8–11. It grows 4–6 ft tall and 2–4 ft wide, so plant it 2.5 ft apart. Give it full sun and little water once established. It flowers blue in January to April. In a FloraVista list it usually plays the structure role: a shrub that holds the bed's shape at the back all year. Deer usually leave it alone, and it is not listed as toxic to dogs or cats.
