Description

Rhododendron 'Unique Marmalade' is a recent variety with evergreen foliage that decorates the garden all year round. It will surprise you with its spring flowering, dominant in orange, changing from red to pink at the tips of the petals. This remarkable bush will be ideal for flower beds or containers.

 

Resulting from the crossing between the Rhododendron 'Orange Marmalade' and the Rhododendron 'Unique', the Rhododendron 'Unique Marmalade' forms an upright habit, reaching 1.2m (4ft) in height with a 1m (3ft) spread. Its evergreen leaves are dark green and elliptical in shape, leathery and elongated, ending in a rounded point. They have a prominent central vein. During the months of April and May, this Rhododendron offers a flowering in corymbs of 6 to 12 flowers. These flowers, dominant in orange, gradually evolve towards red and pink as one approaches the tips of the petals. With its warm-coloured flowering, the Rhododendron 'Unique Marmalade' will brighten and bring a touch of originality to shaded areas.

 

The Rhododendron 'Unique Marmalade' is hardy down to -15°C. It prefers a semi-shaded exposure. Slow-growing, this bush likes fresh, humus-rich and well-drained soils with an acidic tendency.

The Rhododendron 'Unique Marmalade' will be ideal in the middle of a flower bed, in the undergrowth or as a standalone, but always in semi-shade. It will decorate your garden all year round and brighten it. In spring, it will be adorned with remarkable and luminous flowers in shades of orange, red and pink against its dark green foliage. Plant it on a slope or in a rock garden in the company of Ferns, Pieris, Heathers, Kalmias, Japanese Azaleas, and Japanese Maple.

Planting and care

Plant the Rhododendron 'Unique Marmalade' in a semi-shaded position, protected from cold and drying winds, in a moist, humus-rich and light soil, with a tendency towards acidity. Like all plants that prefer acidic soil, 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 leaf compost, gravel or pumice, and loam. Water generously and keep the soil moist in summer. Azaleas and Rhododendrons have a shallow root system. Therefore, they are susceptible to long periods of drought. That's why it is recommended to enrich the soil with humus and water abundantly during dry periods. In addition, this root system is not very strong, which is why it is essential to lighten heavy soils with draining materials (gravel, pumice, clay pellets) at planting. Apply a mulch of shredded pine bark around the base of the bush every spring to keep the soil cool while maintaining an acidic pH. Maintenance involves removing faded flowers in summer and clearing the plant of dead branches. Azaleas and Rhododendrons can sometimes be attacked by weevils, which eat the edges of the leaves and rootlets, as well as the notorious "rhododendron beetle," which rarely causes severe damage. Yellowing of the leaves (chlorosis) in Rhododendrons indicates poor assimilation of iron from the soil and can lead to 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.
