The genus rhododendron consists of many species but Rhododendron canescens gives the most beautiful flowers of all of them. The word canescens is from the latin ‘canescen’ which means ‘becoming gray’. This refers to the dense hairs found on the twigs and leaves of this plant, giving them a grey appearance. It is quite easy to identify this plant from its pubescent leaves, the densely hairy twigs and the light pink to dark purple flowers it shows. It is commonly known by gardeners as Pinxter azalea.

It has alternate leaves that have short hairs on the margins. It can grow to heights between six and fifteen feed and widths between six to ten feet. It is multi trunked and the dark green leaves turn a bright, rusty red colour during the fall.
Fragrant, very showy pink flowers appear at stem ends in early spring, about the time the leaves come out. The corolla tube of the flowers is densely stipitate glandular externally.

The flowers are tubular and spread out into five narrow, lobed petals. The stamens and pistils extend in arching curves over the corolla, which is densely glandular on the outside. Sometimes these plants have flowers that are almost pure white with just a slight tinge of pink, but more often that not the flowers are a rosy pink colour. The plant flowers from March to May.
