Wow!!! I'm chuffed; even lovelier than I hoped, a lighter shade, with a darker pink centre, it's my first rhododendron!!! Received in great shape, I'm delighted! So much so, I've ordered another different one so they can make a lovely pair!!!

Description
The Rhododendron 'Moser's Maroon' is an absolutely stunning old hybrid. With its large, glossy flowers of intense garnet-red, with a black blotch and a cluster of whitish stamens, it is perfect for bringing the garden to life in spring. This foliage of this variety is particularly distinctive due to the carmine-red colour of its spring shoots, which later turn a lustrous dark green. Its evergreen foliage, with its changing colours extends the season of interest for this beautiful shrub. With its dense, upright habit, it will look great in an ericaceous bed or a large container, in partial shade or even in full sun!
Rhododendrons are plants of the Ericaceae family, just like heathers, preferring predominantly chalk-free and slightly acidic soils, as well as damp climates. 'Moser's Maroon' was introduced in the early 20th century. In 1932, it received the prestigious RHS Award of Garden Merit for its ornamental qualities and performance in the garden. It naturally forms a dense bush with a distinctly upright habit, reaching about 2m (6.56 ft) in height and 1.50m (4.92 ft) in spread. It is fairly slow growing. Its dark green, evergreen leaves, which change colour, have a slightly satin finish and are elliptical in shape, covering the plant well. They have a very downy underside. The young leaves are a beautiful carmine-red to purple. In May-June, its remarkably abundant flowering overwhelms the bush: beautiful and large bell-like flowers bloom in voluminous corymbs. Their intense garnet-red colour, mottled with dark purple, is enhanced by the glossy texture of the petals and the white tips of the stamens, like little jewels clustered at the heart of the flower.
The Rhododendron 'Moser's Maroon' is a lustrous shrub, hardy down to -15°C (5 °F) or even -20°C (-4 °F) and easy to grow as long as the conditions suit it in terms of soil and climate. Although they prefer partial shade, large-flowered hybrid Rhododendrons can tolerate the sun as long as it is not too intense and their base remains cool and moist. 'Moser's Maroon', with its prolific, dazzling flowers, will dress up any small partially-shaded area of the garden, terrace, or balcony. Plant it together with ferns, blue or variegated hostas, Pieris, heathers, Kalmias, Azaleas, and Japanese Maples, or other rhododendrons from the same group to create superb patchworks of textures and colours in spring. Growing it in a container requires regular watering with non-alkaline water and specific fertilizer for ericaceous plants.

Planting and care
Plant the Rhododendron 'Moser's Maroon' in a semi-shaded position, protected from cold, drying winds, in a light, moist, acid to neutral, humus-rich soil. Like all ericaeous plants, it does not tolerate chalky or heavy soils waterlogged in winter. If the soil remains moist in summer, this Rhododendron will also tolerate some exposure to a moderate sun. Avoid planting at the foot of the Rhododendron, as its shallow roots do not respond well to competition from other plants, particularly for water.
Dig a hole three times larger than the pot. Soak the root ball in alkaline-free water and plant it so the base of the stem is at soil level, in a mixture composed of 1/4 peat, leaf mould, horticultural grit or perlite and loam. Water generously and keep the soil moist in summer. Azaleas and Rhododendrons have a shallow root system. As a result, they are sensitive to long periods of drought. That is why a soil enriched with humus and generous watering during dry periods is recommended. In addition, this root system is not very strong, which is why it is essential to lighten heavy soils with free-draining materials (horticultural grit, perlite, clay pellets) when planting. Apply a mulch of shredded pine bark around the base of the shrub every spring to keep the soil moist while maintaining an acidic pH.
Maintenance consists of removing faded flowers in summer and clearing out dead branches. Azaleas and rhododendrons can sometimes be attacked by weevils that eat the edges of the leaves and rootlets, as well as by the famous "Rhododendron lace bug", not usually causing significant damage. Yellowing of the leaves (chlorosis) in Rhododendrons indicates poor uptake of iron from the soil and causes premature plant death. While chalk 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.
