Rhododendron

Rhododendron

From the giant rhododendrons of East Asian mountainsides to the rosebay rhododendron native to Eastern U.S. woodlands, this family of plants contains something for every landscape, if provided with moisture and shelter under trees. Large, leathery leaves that persist through winter distinguish a rhododendron from the smaller azalea. Clusters of bell-shaped rhododendron flowers, often fragrant, appear in early to late spring on both plants. Many deciduous azaleas form flowers before the leaves unfurl.

Some azaleas bloom twice a season, on old wood in spring, then on new wood in late summer to fall. To grow rhododendron, ensure the plants receive adequate moisture and a well-drained acidic soil.
