| Upright, very hardy, deciduous shrub with elliptic to oblong, 2 to 6 inch long leaves. Single, trumpet-shaped, white flowers with yellow throats, 2 to 3 inches wide. Flowers are borne in huge, showy trusses of 18 to 30 blooms per cluster. Hardy plant. Bloom time is from early to mid 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. |
