Rhododendron impeditum 'Ramapo' is a compact bush adorned with evergreen leaves, shiny and grey-green with a bluish hue. This spring variety will surprise you with its superb flowering in shades of mauve to lavender. It thrives in the sun in cooler regions, or in partial shade. An acidic and moist soil is essential for successful cultivation. Forming a low and spreading bush, this graceful little rhododendron is perfect for small gardens. Very hardy, it can also be grown in a container to decorate a terrace.
Rhododendrons are plants from the Ericaceae family, which includes a hundred genera, many of which are widespread in our gardens. Heathers, Kalmia, Andromeda, Leucothoe, Oxydendrum or Gaultheria are precious in ornamental beds, while Arbutus and especially Blueberries delight us with their fruits. In the vast majority, these are plants that prefer soils devoid of limestone, with an acidic tendency and humid climates.
Resembling an Azalea in its foliage and flowering, Rhododendron impeditum 'Ramapo' forms a dense and spreading bush, 60cm (24in) high and 1m (3ft) wide at maturity. Its small evergreen leaves have a beautiful glossy appearance and range in colour from green to blue and grey. Elliptical in shape, they are slender and leathery, with a fairly prominent central vein.
During the months of April and May, this bush flowers in clusters of 3 to 6 flowers, sometimes more, in shades of lavender to pink-mauve. This magnificent display lasts for about 3 weeks. Very hardy down to around -24°C, this Rhododendron impeditum 'Ramapo' shows slow growth.
The 'Ramapo' Rhododendron will be ideal in a border, in a pot, or even as a standalone plant in a small garden. For planting in a container, choose a pot made of terracotta or "double skin" if it is a plastic model. This insulating layer of air will prevent the substrate from overheating in summer, which can be detrimental to the roots. Also, remember to water very regularly in this case, as container cultivation is more stressful than in open ground.
In beds, this miniature Rhododendron will occupy the foreground, in front of taller plants of the heath family, such as the beautiful Kalmias, or Mountain Laurels, with their beautiful dark green foliage and lovely small flowers in May-June. It will also thrive in the light shade of an Oxydendrum arboreum, whose summer flowering in long clusters of white bells and dazzling autumn foliage will provide a spectacle for much of the year. And 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 will enchant you from November to January...

Botanical data
Plant the 'Ramapo' Rhododendron impeditum in a sunny (in cooler areas) to partially shaded (in hotter areas) location, protected from cold and drying winds, in a moist, humus-rich and light soil with an acidic tendency (pH between 4.5 and 6). Like all plants of the heath family, it does not tolerate chalky soils or heavy soils saturated with water in winter. And like the majority of rhododendrons, it does not tolerate drought or heatwaves. If the soil remains moist in summer, this rhododendron can also tolerate exposure to non-burning sunlight.
Dig a hole three times larger than the pot. Soak the root ball in non-chalky water for fifteen minutes and plant the bush at the collar level, in a mixture consisting of leaf compost, gravel or volcanic rock, and loam. Water generously and keep the soil moist in summer. Rhododendrons have a shallow root system, therefore, they are sensitive to long periods of drought. That's why it is recommended to have a humus-rich soil and abundant watering during dry periods. Moreover, this root system is not very strong, which is why it is essential to lighten heavy soils with draining materials (gravel, volcanic rock, clay pellets) at planting. Apply a mulch of shredded pine bark around the base of the bush every spring to retain soil moisture and maintain an acidic pH.
Maintenance consists of removing faded flowers in summer and cutting out 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 rarely causes significant damage. Effective biological solutions are available today against weevils. Yellowing of the leaves (chlorosis) in Rhododendron indicates poor iron assimilation from the soil and can lead to premature death of the plant. While limestone (from the soil or irrigation water) is often the cause, poorly drained soil or deeply planted root balls 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.
