Rhododendron Goldflimmer

Rhododendron 'Goldflimmer' is a very unique variety within the genus due to its variegated yellow foliage, which is particularly decorative all year round. In May-June, it produces an abundant and bright flowering that adds to its charm. Large clusters of mauve flowers with brown-yellow spots form at the ends of the numerous branches, attracting all attention in the garden. It is a heathland plant that is sensitive to limestone and drought. It prefers partial shade, but depending on the climate, it can be planted in full sun in the northernmost regions, as long as the soil remains moist.

Rhododendrons belong to the Ericaceae family, which provides us with numerous ornamental plants (Erica, Enkianthus, Kalmia, Zenobia, Oxydendrum...) as well as some fruit-bearing plants (Strawberry tree, Blueberry...). The Rhododendron genus is extremely vast, mainly consisting of bushes, but also including trees over 10 m (33ft) tall, generally with evergreen leaves, but sometimes deciduous, especially in Azaleas, which are, from a botanical point of view, Rhododendrons.

Rhododendron 'Goldflimmer' ('yellow glow') is a hybrid of uncertain origin, resulting from a mutation of a R. ponticum or a R. catawbiense. The plant was isolated and selected by breeder H. Hachmann, a specialist in the Rhododendron genus, in 1983. Variegated foliage is considered rare in these plants, such as the 'President Roosevelt' with pink-red flowers. 'Goldflimmer' is therefore particularly valuable in this regard. It forms a compact bush, around 1.40 m (5ft) tall with an extremely dense habit. Its evergreen foliage, varying from dark to bright green, bears a central yellow macule with irregular edges. This variegation brightens up the mass formed by the bush, especially during dark winter days. Its flowering is equally spectacular as that of other varieties. In May-June, the ends of the numerous branches see the blooming of large clusters of beautiful mauve to lilac-pink flowers, each bearing a discreet brown-yellow spot. The spectacle created by this bright flowering combined with the unique foliage is simply magnificent in late spring.

Rhododendron Goldflimmer, the quintessential heathland bush, will therefore find its place in partial shade in a moist, humus-rich, and well-drained soil with an acidic pH. Hardy to at least -20°C, it will thrive in various regions, but particularly in cool and wet climates. It can be used as a standalone specimen or in mass plantings, alongside other heath plants. You can associate it with numerous other flowering species, choosing varieties with staggered blooming periods to enjoy year-round beauty. Plant a beautiful autumn-blooming Camellia like the stunning 'Yuletide' with bright red flowers from November to January. Also, pair it with the Hamamelis (x) intermedia Westerstede with delicate yellow flowers in February-March and stunning autumn colours. The breathtaking Magnolia Emperor with its giant dark pink flowers will delight you not only in April-May but also in June-July, framing the blooming of 'Goldflimmer'. And for summer blooms, nothing beats the essential Hydrangeas...
