Reblooming azalea 'Encore Autumn Amethyst'

Rhododendron 'Conlee'

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.

Reblooming azalea 'Encore Autumn Amethyst' is an evergreen shrub hardy in zones 6–9. It grows 3–5 ft tall and 3–5 ft wide, so plant it 3.5 ft apart. Give it part sun to part shade and average water. It flowers purple in April to May, September to October. In a FloraVista list it usually plays the structure role: a shrub that holds the bed's shape at the back all year. Deer do eat it, and it is toxic to dogs and cats. Our rules leave it out of lists in the Desert Southwest and the Mountain West, where summer heat, humidity or mild winters hold it back even inside its zone range.
