The plant seems to have taken well but has not flowered yet. I can't wait to see.

Value-for-money
A variety of Rhododendron from the Inkharo range, so more tolerant to clay and limestone. Designed as an alternative to boxwood, it is a dwarf rhododendron that tolerates pruning, has small dense foliage, and forms a very compact bush. A significant advantage is that it is disease-resistant and blooms abundantly in June with small, deep pink flowers, visited by bees. A highly versatile variety to adopt without hesitation in any loose soil, although without excessive limestone content.

Description

The 'Bloombux Magenta' Rhododendron with its small shiny foliage is ideal for low hedges that are pruned, it is a dwarf rhododendron with the soul of a boxwood. In addition, it is part of the Inkharo range: its roots tolerate the presence of clay and limestone in the soil better. It is therefore a non-acidophilous and chameleon-like rhododendron. The Magenta cultivar is adorned with the most intense pink flowers in the Bloombux range. Fragrant and melliferous, they bloom in June on a compact, hardy, and evergreen bush. It can be grown in a pot as well and behaves like a flowering boxwood, resistant to diseases.

Rhododendrons encompass over 800 species from the ericaceae family, cultivated for the beauty of their massive flowering. The story of the Inkharo Rhododendrons, somewhat revolutionary plants recently presented at the Chelsea Flower Show, began in Germany over 20 years ago. The discovery of a rhododendron naturally growing in a chalk quarry made it possible to graft different varieties onto its extraordinary root system. The bushes obtained by this method tolerate a wide range of soils with a pH ranging from 4.5 to 7.5, provided they are loose, fertile, moist, and not excessively chalky. In summary, a soil that suits hydrangeas. The 'Bloombux Magenta' variety is one of the latest introduced to the market and one of the easiest to grow. It is a hybrid between two dwarf species, R. hirsutum and R. micranthum. The bush has a rounded and slightly spreading habit. It will reach about 75cm in height in 10 years, 1m at maturity. Its evergreen foliage is composed of small oval and pointed, entire, dark green leaves with a satin finish. Flowering takes place in June, in the form of terminal clusters composed of a multitude of small flowers ranging from medium to deep pink, slightly fragrant. This plant tolerates pruning just after flowering. It has excellent hardiness.

The 'Bloombux Magenta' Rhododendron is relatively tolerant regarding exposure; we advise you to place it in non-burning sunlight or partial shade, ideally in the east, where it will benefit from morning sun while being protected from excessive heat. In the garden, it can replace boxwood in all its uses: as a hedge, topiary, or in large pots. In a more traditional way, you can plant it alongside many other flowering shrubs, not necessarily acidophilous: hydrangeas, Japanese quinces, smaller buddleias, dwarf Abelias, or autumn camellias. In acid soil, it can of course be associated with Azaleas, Pieris,  Japanese Maples, or, in the back of the border, with Ferns and Japanese Anemones.

Planting and care

Plant the 'Bloombux Magenta' Rhododendron in partial shade, protected from cold and drying winds, in a moist, loose, fertile soil. It will prefer a slightly alkaline, neutral or acidic soil, which is suitable for a hydrangea. Dig a hole three times larger than the pot. Soak the root ball in water and plant the bush at the level of the collar, in a nourishing mixture composed of leaf compost, gravel or pumice, and loam or topsoil, as Inkarho Rhododendrons are hungry plants. Water generously 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. This is why it is recommended to enrich the soil with humus and to water abundantly during dry periods. Apply a layer of wood chips or mulch at the base of the bush every spring to keep the soil cool while maintaining a slightly acidic pH. Maintenance involves removing faded flowers after flowering and cleaning out dead branches. This variety is particularly well-suited for pruning, allowing it to be shaped into a hedge or topiary. Azaleas and Rhododendrons can sometimes be attacked by weevils, which eat the edges of leaves and rootlets, as well as the infamous "rhododendron beetle," which does not often cause significant damage. There are effective natural solutions against weevils. The yellowing of leaves (chlorosis) in Rhododendrons indicates poor assimilation of iron in the soil and can lead to the 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.
