|Upright, hardy, deciduous shrub with elliptic to oblong, 2 to 6 inch long leaves. Single, trumpet-shaped, yellowish-pink flowers with rich yellow blotches, 3 inches wide. Flowers are borne in huge, showy trusses of 15 to 18 blooms per cluster. Bloom time is from mid to late spring.
The deciduous hybrid azalea, like it's native counterpart, is known for excellent fall color and unsurpassed spring flowers. The deciduous azalea is usually less picky about soil conditions, though it too prefers well-drained and acid conditions.
The Knap Hill and Exbury azaleas are English hybrids resulting from crosses between R. molle, R. calendulaceum, R. arborescens, and R. occidentale. 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.
