Rhododendron occidentale (Western Azalea)

Western Azalea, Azalea occidentalis, Honeysuckle Azalea, Pacific Azalea, Late Midseason Azalea, Late Season Azalea


Regarded as the largest flowered, scented, white azalea species, Rhododendron occidentale, commonly known as Western Azalea, is a plant of great beauty and captivating fragrance that appeals to virtually everyone who comes upon it. The large floral trusses are visually compelling with their 5 to 25, flaring, trumpet-shaped, sparkling white flowers, sometimes tinged with pink and marked with a bright yellow to orange spot. In late spring to early summer, the air around the flowers can be delightfully scented with a sweet and spicy clove scent reminiscent of cottage pinks and carnations. Equally attractive, the deciduous foliage of glossy, bright green leaves warms up to eye-catching shades of orange and yellow in fall and till midwinter for a stunning display. This large, spreading and deciduous shrub is native to the western USA (California to S Washington) and the parent of many cultivars and hybrids, including many of the famous Knap Hill Azaleas.

  • Grows up to 6-15 ft. tall and wide (180-450 cm)
  • Winner of the Rhododendron of the Year Award of the American Rhododendron Society for the North West and South West regions.
  • A part shade lover, this plant is easily grown in moist, acidic, humusywell-drained soils. Tolerates full sun in cool moist sites, but does poorly in hot, humid conditions. Plant shallowly in a location protected from strong winter winds. Protect from frost to prevent damage to flowers. Mulch annually with leaf mould to retain moisture, control weeds, and cool the soil.
  • Perfect for shrub borders or mixed borders, as a flowering hedge or privacy screen, foundation plantings and shade gardens.
  • Attracts butterflies, hummingbirds and birds
  • Removing spent flowers promotes new growth.
  • All parts of plant are poisonous if ingested
