This big, spectacular native plant varies from 'Independence' in flower color and bloom time while filling the same niche in large, open shaded areas just as well. 'Roseum' blooms a week to 10 days earlier than 'Independence' unleashing huge lavender-pink flowers in heads of up to 25 blooms in mid to late June, a full 4 to 5 weeks after the bloom of most smaller Rhododendron. These big, showy blooms last into early July and they are backed by long, deep green, strap-like foliage that is loosely arranged on big, wide spreading, open branches. 'Roseum' is a perfect plant for naturalizing in groups along wooded areas or for a showy piece in a large landscape spot with lots of open shade. Make sure the soil is moist but well-drained and 'Roseum' will perform in spectacular fashion.
