Rhododendron catawbiense

Rhododendron catawbiense, with common names Catawba rosebay, Catawba rhododendron, mountain rosebay, purple ivy, purple laurel, purple rhododendron, red laurel, rosebay, rosebay laurel, is a species of Rhododendron native to the eastern United States, growing mainly in the southern Appalachian Mountains from West Virginia south to northern Alabama.
It is a dense, suckering shrub growing to tall, rarely. The leaves are evergreen, long and broad. The flowers are in diameter, violet-purple, often with small spots or streaks, blooming from April through June. The fruit is a dry capsule long, containing numerous small seeds.
The species is named after the Catawba River.

Classification

Rhododendron catawbiense belongs to the subgenus Hymenanthes, within which it is further assigned to section Ponticum and subsection Pontica. The latter—one of the 24 subsections of Ponticum—also contains about a dozen other species. The taxonomy has been confused by a tendency to group all large leaved Rhododendrons under the catch-all R. catawbiense.

Cultivation and uses

Rhododendron catawbiense is cultivated as an ornamental plant, popular both in North America and in parts of Europe. It is primarily grown for its spring flower display. Outside of its native range, many cultivars and hybrids have been created, such as 'Catawbiense Grandiflorum', 'Purple Elegans', 'Roseus Elegans', and 'Grandiflorum'.
