Compact Rhododendrons
Dome-shaped plants ideal for pots and small borders, growing to 75-125cm (2.5-3 foot) in 10 years.
This group consists of Rhododendron yakushimanum and Rhododendron williamsianum hybrids forming mound shaped plants of 75 - 100 cm after 10 years. Williamsianum hybrids normally flower in April with bell shaped flowers and are tolerant of slightly higher pH soils. Yak hybrids mainly flower in May, in rounded trusses which fade gently to a paler colour. They are typically very tough plants, and are ideal for the front of border or for more formal situations in containers.
Most of these varieties are dome shaped plants, wider than their height. Specimen size plants (eg 80-90cm) will typically be measured across the spread of the plant.
