|The artificial species name R. gandavense is often used for all the cultivars of the Ghent hybrids. These hardy plants originated in Belgium and England in the 1800s from crosses between many different species.
The Ghents are tall and broaden with age. They prefer cool climates and are very hardy ( -15 degrees F to -25 degrees F). 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 acid soil. 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.
