Rhododendron

a genus of plants of the family Ericaceae. The plants are small trees or evergreen or deciduous shrubs. The leaves are alternate, entire, and often leathery. The bisexual, five-parted flowers, which have a large, slightly irregular corolla, are gathered into corymbiform or umbellate inflorescences. Less commonly the flowers are solitary. The fruit is a capsule, with numerous small seeds.

There are more than 600 species (according to other data, as many as 1,300), distributed mainly in the temperate zone of the northern hemisphere (predominantly in North America and the mountains of East Asia). The USSR has 20 species, found in the Far East, Siberia, and the Caucasus. R. dahuricum, a branched shrub measuring 0.5-2 m tall, has deciduous leaves and large (2-3 cm) solitary lilac-pink flowers. The species grows in the Far East and Eastern Siberia. R. kamtschaticum is a low deciduous shrub reaching a height of 35 cm and having purple or red flowers that measure up to 4 cm across. The plant grows in Northern Siberia, Kamchatka, Sakhalin, and the Kuril Islands. R. caucasicum, an evergreen shrub reaching a height of 1-1.5 m, has white or cream-colored flowers measuring 5 cm across. It grows in the high-mountain zone of the Caucasus. R. luteum (or Azalea pontica) is a deciduous, highly proliferating shrub. The plant is about 2 m tall and has fragrant yellow or orange flowers reaching 5 cm in diameter. It grows in the mountains of the Caucasus and in isolated areas in the Western European portion of the USSR.

Many species of rhododendron are ornamental. Numerous varieties and garden forms are grown in parks, rock gardens, conservatories, and homes (azaleas). The plants are propagated from seeds, cuttings, and scions. Many species of rhododendron are good nectar bearers, but their honey often is toxic.
