|'Amoenum' is listed as a Kirishimi Azalea and clone of R. 'Obtusum,' which was formerly considered a species but is now regarded as of hybrid origin. 'Amoenum' is also the origin of a group called the Amoena Hybrids developed in the 19th century.
Upright, spreading, dense evergreen shrub with small, oval leaves. Prized for clusters of small, profuse spring flowers that literally cover the plant. Best adapted to partial sun and well-drained, acid soil. Beautiful planted in generous, solid colored drifts along egde of woods. Best if not sheared.
Though azaleas have a potentially large list of possible pest and disease problems, they are usually trouble free if planted correctly in proper cultural conditions.
