Description
Large lilac-purple flower clusters cover Rhododendron Catawbiense Boursault from late spring into early summer. Fine reddish to pale brown markings distinguish the funnel-shaped blooms, while dense dark green foliage forms a broad hedge or privacy screen.
Plant in moist but well-drained, humus-rich acid soil in partial shade, sheltered from harsh afternoon sun. Mulch the root zone, water regularly, and apply acid-loving fertilizer after flowering. The plant is toxic if eaten, so keep pets from chewing it.
