Rhododendron 'Grandiflorum'

Rhododendron 'catawbiense grandiflorum' is a medium-sized, evergreen, rhodo with a vigorous, rounded, upright shape. The leaves are broadly elliptish, smooth, slightly glossy and dark green in color. This catawbiense hybrid blooms mainly from May to June, with bell-shaped, lavender, lilac flowers with light yellow-red spots in the throat, grouped in almost round racemes. This rhododendron prefers a location in filtered sunlight or partial shade, sheltered from harsh winds and with a shaded root zone. It requires an acidic, moist, well-drained soil that should never be allowed to dry out completely, requires little pruning and is hardy.
