The marvellous, full trusses of white, funnel-shaped flowers of 'Cunninghams White' break from flushed-mauve buds in late-spring and contrast beautifully against the dark green leaves, which are retained all-year for added interest!
The upper petal of the blooms is coloured with yellow marking which grade through to greenish-brown and red, making them absolutely stunning when this Rhododenron is in full bloom. For improved and more abundant flowering, dead-head faded blooms where possible and avoid shade which reduces blooming.
This lovely, old hybrid rhododendron is understandably popular, due to its tolerance of poor or near-neutral soil, making it ideal for many gardens. Compact and robust it's ideal for growing on a boundary, for use as a windbreak or screen.
Rhododendrons are low-maintenance shrubs that will perform superbly provided you plant them well and keep them well-watered. They mostly prefer bright to dappled shade or partial shade, avoiding morning sunlight which can damage buds.
Rhododendron roots are shallow, spreading to sides in search for nutrients., so never plant them too deep - remember that they often grow in shallow cracks on mountainsides.
Soil does need to be on the acidic side and rich in humus, cool and always moist which will allow established plants to withstand direct mid-day and afternoon sun.
Supplied as an established plant in a 4L pot, 'Cunninghams White' will reach H2.5m (8ft) x W2.5m (8ft) and suits container growing perfectly.
Rhododendrons have a shallow root systems to quickly capture rainfall, so need to be kept well-watered - mulch to keep them from drying out.
