A beautiful hybrid Rhododendron involving our western azalea, introduced by a Dutch nursery in 1895. This is a deciduous shrub with massive displays of sweetly scented funnel-shaped blossoms in late spring. The large showy trusses have flower buds with dark-pink stripes that open to a light rose-pink with a splash of yellow-orange on its upper petals. Grows 6 -8 ft. tall by 4 – 6 ft. wide in part shade with regular to moderate watering. Prefers humus rich acidic soils with good drainage. The fragrant flowers attract an array of pollinators including butterflies. Deer resistant.
