Description

Grevillea 'Bronze Rambler' is an Australian hybrid that will form a large, evergreen and dense ground cover, particularly sculptural. This variety is adorned with original foliage, cut into large lobes, and beautifully coloured coppery bronze on young shoots: a beautiful setting for its long spring flowering of a deep purple-red. Like many Grevillea, this one thrives in the sun in phosphorus-poor, well-drained, non-chalky soil. It can withstand summer drought once well established but is sensitive to heavy frosts. Well suited to coastal areas, this plant will make a big impact in a large rock garden, raised bed or on a slope.

Grevillea Bronze Rambler is a bush from the protea family resulting from the cross-breeding between the Grevillea rivularis and the 'Poorinda Peter' variety. Many Grevillea species are pioneers in their natural environment: they tolerate fairly poor, dry soils, but do not appreciate the presence of limestone, and require full sun to bloom. Rapidly growing to reach its adult size in 4-5 years, this bush with a low and wide habit will measure about 30 cm (11.8 in) in height and up to 3 m (9 ft 10 in) in diameter. It develops thin ascending branches, forming a dense and slightly bushy mass. Its evergreen leaves are divided into 9 to 11, tough, elliptical segments. They are coppery bronze when they emerge, then turn bright green. Flowering starts in March-April, depending on the climate, and continues until May-June. The very decorative flower buds form as early as the end of autumn. The raspberry-red flowers are composed of petal-like styles curled upon themselves and long curved stamens. They are grouped in upright clusters resembling a toothbrush. The root system of this plant is very dense on the surface, which reflects its adaptation to nutrient-poor soils and summer drought.

Grevillea 'Bronze Rambler' is moderately hardy, it can withstand temperatures down to -6°C (21.2 °F) when planted in sunny and well-drained soil. This bush requires little maintenance after the establishment period. It should be planted in light, filtering, acidic soil. It is a fairly easy plant to acclimate to a sufficiently sunny coast. It can be used as ground cover to decorate a large rock garden, along a path, or on a slope. It can be combined with other prostrate bushes to vary the colours: juniper, ceanothus and creeping rosemary, Nandina Fire power, Mimosa cognata Limelight. In an exotic setting, it can be combined with proteas, agaves, Canary viper's bugloss, Euphorbia mellifera, Aloe aristata...

Grevillea: planting, pruning and care

Read article

Grevillea are ornamental bushes or small trees, evergreen and native to Australia. They have a flowering that is very exotic, taking the form of clusters or corymbs of flowers made of curled filaments which lasts from late winter to autumn, usually peaking in spring. Flower colour ranges through tones of red, pink, yellow, orange or even white. The best known is <a href="https://en.promessedefleurs.eu/shrubs/shrubs-by-variety/grevillea/grevillea-juniperina.html">Grevillea juniperina</a> or juniper-leaf grevillea, characterised by narrow, needle-shaped leaves and bright red spidery flowers. Les grévilléas présentent une grande diversité en terme de taille et de port, allant de l'arbuste prostré de 15 cm de hauteur (<a href="https://en.promessedefleurs.eu/shrubs/shrubs-by-variety/grevillea/grevillea-lanigera-mount-tamboritha.html">Grevillea lanigera Mount Tamboritha</a>) au petit arbre dépassant 10 m dans son habitat mais souvent limité à 2 m de hauteur en culture. Leur feuillage prend une allure tantôt de frondes de fougères, tantôt d’aiguilles de pins plus ou moins épaisses. Leur longue floraison, abondante et singulière, se compose de petites fleurs sans pétales à pistils saillants, réunies en inflorescences terminales qui prendront selon le cas une disposition en araignée, en ombelle, une forme globuleuse, cylindrique ou de "brosse à dents". <img class="alignnone wp-image-53623 size-full" src="https://www.promessedefleurs.com/blogwp/wp-content/uploads/2018/11/Grevillea2.jpg" alt="Grevillea" width="1172" height="780" /> Grevillea, like many other Australian plants, is not difficult to to grow provided conditions are suitable. These cousins of Protea are semi-hardy plants of poor, free-draining, non-calcareous and fairly dry soils, which thrive in open ground in mild climates and are easy to grow in pots elsewhere. Hardiest among them is probably <a href="https://en.promessedefleurs.eu/shrubs/shrubs-by-variety/grevillea/grevillea-rosmarinifolia.html">Grevillea rosmarinifolia</a>, able to withstand short frosts down to around -15°C in very well-drained soil. This Australian bush requires little maintenance and tolerates light pruning which keeps it compact and dense. Plant it without hesitation in coastal gardens spared from severe frosts where, depending on variety, it will form dense, flowering screening hedges for a very long period or a superb cushion on a bank or in rockery for the lowest species and varieties. It is a good plant for dry gardens, requiring an exposed, sunny position. Growing in a container allows both control of growing medium composition and overwintering the bush in an unheated greenhouse or a very bright, lightly heated conservatory.

Planting and care

Culture:

Grevilleas are best planted in spring, after the last frost. In warmer climates, planting in October is better. They prefer soil with an acidic to neutral pH, sandy, gritty, loamy, or slightly clayey, but very well-drained and not too rich. The presence of limestone in the soil causes yellowing of the foliage, chlorosis, which weakens the bush until it eventually dies. This condition can be corrected by regularly adding iron in its chelated form (sequestrene). In regions where the soil and subsoil are limestone, it is recommended to dig a large hole of 60 cm (23.6 in) in all directions, filled with ericaceous soil or compost and non-limestone sand.

Grevilleas are drought-resistant plants once well established: monitor watering in summer may be necessary during the first 2 years, but will become optional or even unnecessary afterwards. In the ground, they appreciate a thick layer of mulch not too close to the base. Use wood chips or grass clippings. It is recommended to use a very low phosphorus fertilizer, as it can decrease the plant's drought resistance by destroying the thick root hairs that develop just below the soil surface. An N-P-K fertilizer with proportions of 18-2-10 is well-suited.

In pots choose Grevillea species and varieties with low growth. Use lightweight, well-drained potting soil that remains moist. We recommend the following mix: 60% pine bark, 20% coarse river sand, 10% fine river sand, and 10% clay soil for its water retention capacity. The pH should be 7 or less.

Insects and Diseases:

Grevilleas can have black leaf spots, caused by a rarely fatal fungus: a fungicidal treatment will eliminate it.

Rotting of the collar can also be seen, a deadly disease, also caused by fungi that develop in moist and warm soil. Avoid burying the plant's collar, which should be exposed to air. Avoid watering too often in hot weather, let the soil dry out between waterings.

Phytophthora (cinnamomi), a disease also caused by a fungus, affects many plants in dry areas. The parasite destroys the roots during excessively rainy winters. The plant may suddenly wither in summer due to a lack of water as a result of the destruction of part or all of its roots. Partial or complete death of the vegetation or branches can be observed in severe cases. Prevention is crucial, as the disease is almost impossible to eradicate: make sure the soil drainage is perfect, remove the water from the saucer placed under the pot, and remove dead or diseased parts.

Pruning:

Grevilleas tolerate annual pruning well, during their growth period or just after flowering. Shorten the branches by one-third of their length. A regularly pruned bush will be more branched and more floriferous.
