After years spent hybridizing Rhododendrons, David Leach was successful in developing one of the best yellow flowering varieties. The Capistrano Rhododendron is a dense plant with a rounded form clothed in glossy, deep green foliage that serves as the perfect backdrop for the abundant and large orb-like clusters of clear yellow flowers that warm the garden in spring. At 4 to 5 feet tall and wide, plant this charming beauty as a focal point specimen in smaller beds or in mixed landscape and woodland borders. Cold hardy to -20F and easy to grow.
