Product Description

The marvellous, full trusses of pure white, funnel-shaped flowers of 'Madam Masson' burst open in May and June and contrast beautifully against the dark green leaves, which are retained all year.

The upper petal of the flowers is splashed in mustard yellow speckles, making them absolutely stunning when this Rhododendron is in full bloom. For improved and more abundant flowering, deadhead faded blooms where possible and avoid heavy shade which reduces blooming.

Fully deserving its coveted RHS Award of Garden Merit, you can be sure that this is a proven garden performer, guaranteed to be suitable for UK gardeners at every level of experience. You can therefore plant this in the garden with confidence, for stunning displays for many years to come.

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 the 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 21cm pot, 'Madam Masson' will reach a height and spread of 2m (6½ ft).

Plant Information

Top Tips

  • Deadhead faded blooms where possible and avoid deep shade, as this will reduce flowering.
  • Perfect for growing in a large container using ericaceous compost, just make sure that you feed and watered well and re-pot every couple of years.

Care Guide

  • Rhododendrons can tolerate a more open site as long as they are sheltered from cold, drying winds and early morning sunlight. Mulch plants and water deeply and regularly during dryer periods from July onwards.
  • Your Rhododendron should be planted slightly higher than it was in its pot into well-draining soil.
  • Rhododendrons need an acidic soil with a pH of around 5.5 in order to thrive - soils with pH higher than 5.5 should be acidified before planting or you can grow them in a container with ericaceous compost.
  • Keep plants well-watered and apply a mulch to prevent the soil from drying out.
