Quick Overview:

‘Boursault’ is a dense, upright, evergreen rhododendron. It has violet buds that open into lavender flowers with some reddish or pale brown spots. It will grow 6 feet tall in 10 years but eventually can grow to 10-15 feet tall.

Description

Best grown in acidic, humusy, organically rich, medium moisture, moisture-retentive but well-drained soils in part shade to full shade. Prefers a sun dappled shade. Plant in a location protected from strong winter winds. Good soil drainage is essential (doesn’t like “wet feet”). Poor drainage inevitably leads to root rot, therefore raised beds/plantings should be considered in heavy clay soils. Shallow, fibrous root systems (do not cultivate around plants) will benefit greatly from a mulch (e.g., wood chips, bark or pine needles) to help retain moisture and stabilize soil temperatures. Roots must never be allowed to dry out. Acidify soils as needed. Clip off spent flower clusters immediately after bloom as practicable.
