Extra information:

The name 'albrechtii' commemorates Michael Albrecht, a physician at the Russian
consulate in Hakodate, on the island of Hokkaido, Japan. 
Albrecht discovered this azalea growing near Hakodate in 1860.
It was described by the botanist Maximovicz in 1870, but was not 
introduced to cultivation in the west until Professor Charles Sargent, 
first director of the Arnold Arboretum, sent seeds to the Arboretum in 1892.
A subsequent collection of seed by E. H. Wilson in 1914 was distributed
by the Arboretum. In nature it occurs from central Honshu 
northward to Hokkaido, at elevations of 2,500 to 6,500 feet.

Rh. albrechtii is a deciduous azalea. 
The color varies from a deep rose pink to brilliant red-purple.
