Description

Rhododendron Easydendron® Inkharo® Madame Masson is originally an excellent old variety, appreciated and awarded. It has been grafted onto "Inkharo" to show improved tolerance to slightly chalky or clayey soils. It forms a rounded bush with elongated, shiny green leaves, with abundant, white spring flowers, spotted with golden yellow. This very hardy, early flowering selection formerly reserved for acid soil beds, can now be planted in a wider variety of conditions, even in slightly chalky or heavy soils. If your soil is acidic, choose Rhododendron Madame Masson on its own roots.

Rhododendrons are plants from the ericaceae family, just like heathers. The history of Inkharo Rhododendrons, somewhat revolutionary plants, began in Germany over 20 years ago. The discovery of a rhododendron naturally growing in a chalk quarry made it possible to consider grafting different varieties onto its extraordinary root system. The bushes obtained through this method tolerate a wide range of soils with a pH ranging from 4.5 to 7.5, as long as they are loose, fertile, moist, and not excessively chalky. In summary, a soil that would be suitable for hydrangeas. The Madame Masson cultivar, originally derived from a cross between Rhododendron catawbiense and Rhododendron ponticum, forms a large branching bush with a dense habit, reaching approximately 1.30 m high at 10 years and 1.30 m in width, under good growing conditions, in open ground. Its growth is rather slow. Its large leaves are elliptical, dark green and glossy on the upper side, with a lighter,hairy underside. They persist in winter. Towards the end of April, for approximately 3 weeks, large clusters or spherical corymbs of flower buds bloom at the ends of the branches. They open into well-shaped, open corolla flowers. The heart of the flower is spotted and speckled with golden yellow and has long white stamens. The petals are white.

Rhododendron Inkharo Madame Masson is a very hardy plant, down to approximately -20°C. It prefers a shaded exposure. In the garden, with its abundant and delicate flowering, it easily decorates a shaded area of the garden, in the company of Ferns, blue or variegated hostas, Pieris, shrubby heathers, Kalmias, Azaleas and Japanese maples, or other rhododendrons from the same group to create beautiful patchworks of textures and colours. You can also plant it alongside many other flowering shrubs, not necessarily acid-loving: hydrangeas, autumn camellias. Japanese Anemones will also be good companions, as well as bugbanes and foxgloves, in woodland areas.

Planting and care

Plant the Rhododendron Inkarho Madame Masson in a semi-shaded location, protected from cold and drying winds, in moist, loose, fertile soil. It should be slightly calcareous, neutral or acidic, a soil that will suit a hydrangea. Dig a hole three times larger than the pot. Soak the root ball in water and plant the bush at the neck level, in a nourishing mixture composed of leaf compost, gravel or pumice stone, and loam or topsoil, as Inkarho Rhododendrons are hungry plants. Water thoroughly and keep the soil moist in summer. Azaleas and Rhododendrons have a relatively shallow root system. As a result, they are sensitive to long periods of drought. That is why soil enriched with humus and abundant watering during dry periods are recommended. Apply a layer of wood chips or mulch at the base of the bush every spring to maintain soil moisture while keeping the pH slightly acidic. Maintenance consists of removing faded flowers after flowering and cleaning dead branches.

Azaleas and Rhododendrons can sometimes be attacked by weevils that eat the edges of the leaves and rootlets, as well as the infamous "rhododendron beetle" which usually does not cause significant damage. There are effective natural solutions against weevils. Yellowing of the leaves (chlorosis) in Rhododendrons indicates poor assimilation of iron in the soil and can lead to premature death of the plant. While limestone is often the cause, poorly drained soil or a deeply planted root ball can also explain the phenomenon.
