Caroline Allbrook is a compact yakushimanum rhododendron of attractive habit and possible the most sought-after flower colour among all yakushimanums. It forms a neat evergreen shrub with elongated, leathery foliage, above which open rich trusses if dark lilac pink flowers that fade to soft, very pale lavender violet colour. Flowering begins in late May and continues until early June. Bred by A.F.George from Hydon Nurseries in 1975. Caroline Allbrook rhododendron takes full sun as well as partial shade.

In order to keep the plants looking nice and clean dead-head where possible. The roots are shallow, spreading to sides in search for nutrients. Never plant them too deep. The soil has to be acidic, rich in humus, cool and always moist. Ideal soil mixture is peat with lime-free, light garden soil topped with leave-mould. Use selective fertilizers for rhododendrons only. Place it in full sun or partial shade. Hardy to abt. -27°C (USDA zone 5b).
