Adding glorious color, Rhododendron macrophyllum (Pacific Rhododendron) is a large, upright branching, evergreen shrub boasting spectacular trusses of 10-20 bell-shaped pale to deep pink flowers, 2 in. across (5 cm), in mid-spring to mid-summer. This is the showiest flowering shrub in the forests of western North America, with flower clusters that nearly rival in size and number those of its cultivated relatives. The charming blossoms appear above large whorls of deep green, egg-shaped to oblong leaves, 3-8 in. long (8-20 cm), with a smooth, leathery texture. The shrub is erect to spreading with stout branches. It tends to grow tall with an open habit when in the shade of large conifers but will stay smaller and more compact in areas where it gets more sun. Often grown as an ornamental, Pacific Rhododendron is a splendid and dramatic large foundation plant that is native to western North America.
