Rhododendron Luteum

The generic name is derived from the Greek words rhodos, meaning rose, and dendron, meaning tree. Today this very large genus botanically includes also the azaleas (from the Greek word azaleos, meaning dry), which, unlike the evergreen rhododendrons, are mostly deciduous. The genus includes some thousand species, the majority of which are found in China and Japan.

Rhododendrons are usually shrubs, occasionally trees. The leaves are deciduous or evergreen, entire on the margin as a rule, very occasionally slightly serrate, tough and leathery, and usually darker above than below. The flowers are borne in terminal racemes, or else singly or several together on lateral branchlets, and are usually tubular in shape. The blossoms are in most cases irregular, asymmetrical.

Rhododendron luteum, also listed as Azalea pontica and Rhododendron flavum, is a deciduous species that previously belonged to the azalea group. It is native to eastern Europe, the Caucasus and Asia Minor. A shrub of loose form, it grows to a height of 4m (13 ft). The yellow, very fragant flowers are borne in terminal racemes and appear in May. This is a very hardy species and is used as rootstock for grafting hybrids.
