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 turns 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 is the parent of many cultivars and hybrids, including many of the famous Knap Hill Azaleas.
