| The Ilam azaleas are hybrids developed in New Zealand from crosses between R. molle, R. calendulaceum, and R. viscosum. Upright, deciduous shrub that is cold hardy from -10 to -20 degrees F. Leaves are elliptic to oblong, 2 to 6 inches long. Flowers are borne in compact trusses of 7 to 9 flowers from early to late spring. The deciduous hybrid azalea, like its 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. 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. |
