|R. luteum, otherwise known as the Pontic azalea, is a tall, deciduous shrub with oblong to lance-shaped leaves 2 to 4 inches long. Yellow, strongly fragrant flowers, 1 to 1 1/2 inches across are borne in trusses of 7 to 12 per cluster. Prefers full sun.
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 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.
