Capistrano rhododendron

Rhododendron hybrid 'Capistrano'

Photo gallery1 photo

Rhododendron 'Capistrano' forms a dense, mounding evergreen shrub with deep green leaves and pale greenish-yellow spring flowers gathered in rounded clusters. It generally reaches about 3–5 feet tall and 5–6 feet wide; a height of about four feet at ten years is an age-based observation, not its final size. Give it room in a partly shaded shrub border, where its foliage can provide structure through the year. Partial shade, especially afternoon shade, and acidic, moist, well-drained soil suit this cultivar. Mulch over its shallow roots and leave the soil beneath the branches undisturbed.

The right plant, the right place

Make room for something good.

The dense, mounding form brings evergreen structure to a partly shaded shrub border. Allow room for its broad spread rather than crowding it against nearby plants.

Where to plant

Choose partial shade, with protection from afternoon sun. Allow at least about 5–6 feet for its expected spread, and more where space is tight.

Through the seasons

Rounded clusters of pale greenish-yellow flowers appear in spring. Deep green leaves remain through the year.
