Ilam azaleas are a group of very hardy deciduous shrubs produced in New Zealand that can withstand temperatures between -10 and -20 degrees F. The deciduous hybrid azalea, like it's native counterpart, is known for excellent fall color and unsurpassed, profuse, early spring flowers. The deciduous azalea is usually less picky about soil conditions, though it too prefers 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.
