Rhododendron occidentale is an azalea native to parts of Southern Oregon and Northern California, along the coast. Many cultivars have been selected over the years. The plant in Ed's garden was most likely planted in the early 1950's. Fragrant flowers in mid to late May scent the air for quite a distance. This plant gets some mildew in the garden, but not enough to draw one's attention. Fall coloration is decent and we try and deadhead the plant every year, as the spent seedpods detract from the flowers.
