Rhododendron hirsutum was the first rhododendron to be classified and named. It was discovered in the 16th century by a Flemish botanist, Charles l'Ecluse, who later became called Clusius.
The purpose of this website is to give an overview of as many rhododendron species and hybrids as possible. A virtual botanical garden. A virtual arboretum.
Species (the originals found in nature) include azaleas and vireyas, since they became part of the Rhododendron-genus as well. For the species see also the classification-rules.
