Rhododendron hybrida ( Crinoline Glenn Dale Azalea )

Upright to widely spreading, evergreen azalea developed primarily for cold hardiness along the mid-Atlantic states. Single, funnel-shaped, ruffled, rich mauve flowers, 3 inches wide. Flowers are borne in showy trusses of 1 to 4 per cluster. Bloom time is late April in warmer areas and as late as early June in cooler climates. Plant as you would any of the other azaleas: high and in well-drained, acid soil, rich with organic matter. This is usually a back of the border azalea because most of the Glenn Dales are taller, though not all. Filtered light is best. 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.
