Rhododendron catawbiense 'Roseum Elegans' is a slow-growing evergreen shrub for gardens in zones 4–8. It grows 6–8 ft tall and 6–8 ft wide, so plant it 6.5 ft apart. Give it part sun to shade and average water. It flowers purple and pink in May to June. In a FloraVista list it usually plays the anchor role: the one larger plant that anchors the back of a bigger bed. Deer do eat it, and it is toxic to dogs and cats. Our rules leave it out of lists in Florida and the Gulf, Texas and the South-Central states, the Desert Southwest and the Mountain West, where summer heat, humidity or mild winters hold it back even inside its zone range.
