Rhododendron Easydendron ® INKARHO English Roseum
Rhododendron, Azalea
Planted in spring, it took a while to get going and didn't produce any flowers this year. I'm eagerly awaiting next spring to see it bloom.

Description
Rhododendron Easydendron English Roseum Inkarho is a reliable and robust variety, appreciated and awarded. It has been grafted with "Inkharo" to show improved tolerance to slightly limestone or clayey soils. It forms a rounded bush of beautiful stature with elongated, shiny green leaves, boasting a spring flowering so abundant that its foliage is almost hidden. Its large, lilac pink flowers are speckled with orange-brown. Gifted with good cold resistance, but also heat resistance, a quality not so common in these plants, this selection once reserved for ericaceous soil beds can now be planted in a wider variety of conditions, even in slightly limestone or heavy soils. With its lush appearance, this large bush creates superb screens at the back of flower beds or majestic evergreen hedges.
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 led to the consideration of grafting different varieties onto its extraordinary root system. Shrubs 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 calcareous. In summary, a soil suitable for hydrangeas. The English Roseum cultivar forms a large bush with a slightly spreading rounded habit, as wide as it is tall. Its growth is relatively fast, reaching an average of 2 m in all directions (sometimes up to 2.50 m in span) in good conditions. The branches are abundantly covered with beautiful glossy dark olive green, narrow, slightly arched, oblong-shaped evergreen leaves. The remarkably abundant flowering occurs from late May to mid-June. The large flowers are grouped in large spherical clusters, with up to 10 funnel-shaped flowers. The colour of the flowers at blooming is a rich pink. Over time, they take on a more mauve hue and reveal a bronzed speckled throat occupied by long curved pink stamens.
Rhododendron English Roseum Inkarho is a very hardy plant, down to approximately -25°C. It will thrive in partial shade in moist, humus-bearing, loose soil. In the garden, with its abundant and delicate flowering, it easily dresses up a shaded area of the garden, alongside Ferns, blue or variegated hostas, Pieris, shrubby Heathers, Kalmias, Azaleas, and Japanese maples, or other rhododendrons from the same group to create superb patchworks of textures and colours. It is versatile and 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 the undergrowth. In a large garden, it could even form a majestic hedge along a grand avenue, alongside other large rhododendrons.

Planting and care
Plant the Rhododendron Easydendron English Roseum Inkarho 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 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 collar level, in a nourishing mix composed of leaf compost, gravel or pumice, and loam or topsoil, as Inkarho Rhodos are nutrient-demanding plants. Water generously and keep the soil consistently moist. Azaleas and Rhododendrons have a relatively shallow root system. As a result, they are sensitive to long periods of drought. Therefore, soil enriched with humus and abundant watering during dry periods are recommended. Apply a mulch at the base of the bush every spring to maintain soil moisture while keeping a slightly acidic pH. Maintenance involves removing faded flowers and dead branches.
Azaleas and Rhododendrons can sometimes be attacked by vine weevils that eat the edges of leaves and rootlets, as well as by the infamous "rhododendron borer" which does not often cause severe damage. There are effective natural solutions against vine weevils. Leaf yellowing (chlorosis) in Rhododendrons indicates poor iron assimilation in the soil and can lead to premature plant death. While limestone is often the cause, poorly drained soil or a deeply planted root ball can also explain the phenomenon.

Hardiness is the lowest winter temperature a plant can endure without suffering serious damage or even dying. However, hardiness is affected by location (a sheltered area, such as a patio), protection (winter cover) and soil type (hardiness is improved by well-drained soil).
In temperate climates, pruning of spring-flowering shrubs (forsythia, spireas, etc.) should be done just after flowering.
Pruning of summer-flowering shrubs (Indian Lilac, Perovskia, etc.) can be done in winter or spring.
In cold regions as well as with frost-sensitive plants, avoid pruning too early when severe frosts may still occur.
The harvesting period indicated on our website applies to countries and regions in USDA zone 8 (France, England, Ireland, the Netherlands).
In colder areas (Scandinavia, Poland, Austria...) fruit and vegetable harvests are likely to be delayed by 3-4 weeks.
In warmer areas (Italy, Spain, Greece, etc.), harvesting will probably take place earlier, depending on weather conditions.
The sowing periods indicated on our website apply to countries and regions within USDA Zone 8 (France, UK, Ireland, Netherlands).
In colder areas (Scandinavia, Poland, Austria...), delay any outdoor sowing by 3-4 weeks, or sow under glass.
In warmer climes (Italy, Spain, Greece, etc.), bring outdoor sowing forward by a few weeks.
The planting period indicated on our website applies to regions in USDA Zone 9a (East Coast and Midlands: Dublin, Wexford, Waterford, Kilkenny, Portlaoise). It will vary depending on where you live:
- On the west coast and in the north-west (Galway, Limerick, Sligo, Donegal, Westport), delay planting by 1 to 2 weeks in spring and bring it forward by 1 to 2 weeks in autumn compared to the dates given, preferably choosing periods without strong winds.
- In the inland hills and plateaus (Wicklow Mountains, Macgillycuddy’s Reeks, Connemara, Killarney), it is best to plant in spring (April–May) or autumn (September–October), avoiding periods of waterlogged soil in winter and strong winds, which pose the main risk to newly planted trees in these areas.
The flowering period indicated on our website applies to regions in USDA Zone 9a, such as the East Coast and Midlands, including Dublin, Wexford, Waterford, Kilkenny and Portlaoise.
This will vary depending on where you live:
- On the west coast and in the northwest (Galway, Limerick, Sligo, Donegal and Westport), it will be delayed by one to two weeks compared to the given dates, due to stronger Atlantic winds and less spring sunshine.
- In the inland hills and plateaus (the Wicklow Mountains, the Macgillycuddy's Reeks, Connemara and Killarney), flowering will be delayed by two to three weeks. Flowering mainly occurs between May and July, with the limiting factors being less frost and more of the excessive humidity, strong winds and lack of sunshine that are characteristic of these areas.
