Description
Rhododendron Blewbury is an exceptional variety of dwarf rhododendron. Its fantastic white spring flowering covers a lovely elliptical foliage that is slightly convex and pointed with curled edges. The first ornaments in late winter are its bright pink buds. Then, for a long month, from mid-April to mid-May, clusters of 18 to 20 bell-shaped flowers, white with a wine-coloured mark, giving a washed-out pink appearance, almost completely invade the elegant bush. This variety has received an Award of Garden Merit from the Royal Horticultural Society in England. With remarkable elegance and radiance, this little "rhodo" stands out as much as a larger plant in gardens of all sizes.
Rhododendrons are plants of the Ericaceae family, which includes about a hundred genera, many of which are common in our gardens. Heathers, Kalmia, Andromeda, Leucothoe, Oxydendrum, or Gaultheria are valuable in ornamental beds, while Strawberry Trees and especially Blueberries delight us with their fruits. For the most part, these are plants that prefer soils devoid of limestone, with an acidic tendency and humid climates.
Rhododendron Blewbury comes from a rare cross between Rhododendron roxieanum var roxieanum and maculiferum ssp anwheiense. It forms a dense bush with a rounded habit, reaching 80 cm in height and 90 cm in width at maturity. Its evergreen leaves are elliptical in shape, slender, and leathery with curled edges. During April and May, longer flowering than most rhododendrons invades this dwarf shrub, which is literally covered with bright pink floral buds that then open into white flowers about 3.5 cm in size, shaded with light pink, thanks to their wine-coloured markings. The flowers are grouped in terminal clusters composed of 18 to 20 flowers.
Hardy down to -22°C, Rhododendron Blewbury prefers a semi-shade or dappled shade exposure. With slow growth, this acid-loving ericaceous shrub thrives in moist, humus-rich, well-drained soils. It is ideal as a border plant, in a pot, or even as a standalone specimen in a small garden. In a bed, this miniature Rhododendron occupies the foreground, in front of taller acid-loving plants, such as beautiful Kalmias, or Mountain Laurels, with their dark green foliage and pretty small flowers in May-June. It also thrives in the light shade of an Oxydendrum arboreum, whose long clusters of white bells in summer and vibrant autumn foliage provide a spectacle for much of the year. To ensure flowers all year round, complete this picture with an Autumn Camellia like the magnificent Camellia sasanqua Yuletide, whose bright red flowers with yellow stamens enchant your days from November to January.

Planting and care
Plant Rhododendron Blewbury in a sunny or partially shaded location, protected from cold and drying winds, in moist, humus-rich, light soil with an acidic tendency. Like all plants of the heath family, it does not tolerate limestone soils or heavy soils that become waterlogged in winter. Dig a hole three times larger than the pot. Soak the root ball in non-limestone water and plant the bush at the collar level, in a mixture composed of 1/4 organic matter, leaf compost, gravel or pumice, and loam. Water thoroughly and keep the soil moist in summer. Azaleas and Rhododendrons have a shallow root system. As a result, they are susceptible to long periods of drought. That's why humus-rich soil and abundant watering during dry periods are recommended. In addition, this root system is not very strong, so it is essential to lighten heavy soils with draining materials (gravel, pumice, clay pellets) at planting. Apply a mulch of shredded pine bark at the base of the bush every spring to maintain soil moisture while preserving an acidic pH. Maintenance consists of removing faded flowers in summer and cleaning dead branches. Azaleas and Rhododendrons can sometimes be attacked by weevils that eat the edges of leaves and rootlets, as well as the infamous "rhododendron beetle" which does not often cause severe damage. Yellowing of the leaves (chlorosis) in Rhododendron indicates poor assimilation of iron 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.
