Introducing Grevillea ‘Bronze Rambler’ 

Grevillea ‘Bronze Rambler’ is a hybrid between Grevillea rivularis and Grevilliea ‘Poorinda Peter’. G. rivularis (Carrington Falls grevillea) is threatened in its natural habitat, but its striking foliage is well represented in its trailing offspring, while the selectively bred Grevillea ‘Poorinda Peter’ lends its flower form and sprawling habit to Grevillea ‘Bronze Rambler’.

Natural Habitat of Grevillea ‘Bronze Rambler’

Like all grevilleas, Bronze Rambler has its origins in Australian soil, but as a man made hybrid, it is not actually native to anywhere. Thankfully, with its mixed parentage, it is very well suited to Australian gardens, and grows well in almost all parts of the country.

How to Grow Grevillea ‘Bronze Rambler’

Grevilleas are native plants, preferring full summer sun, but able to cope with some shade. Over winter, this plant can be left outside even in frosty parts of the county as it is fully frost-hardy.

Plant Grevillea ‘Bronze Rambler’ into enriched soil to get it off to the best start, preparing a planting hole that is twice the size of its root ball. Loosen the soil at the base of the hole and mix compost back through the soil before in-filling around the roots.

Note: Propagating Grevillea ‘Bronze Rambler’ is surprisingly simple. Check out our guide to growing Grevilleas for a guide on seed and cutting propagation.

Soil & Drainage

Choose a spot with good drainage. Like all grevilleas, Grevillea ‘Bronze Rambler’ will suffer from damp problems, root rot, and fungal infection in overly wet soil. If you have a damp garden, you can still grow Grevillea ‘Bronze Rambler’ in pots to provide drier conditions.

There is little need for fertiliser after initially planting with some compost to support initial root growth, but if you notice yellowing or crisping leaves as a result of nutrient deficiency, add phosphorus to the soil, either through organic feed or any basic native plant fertiliser.

Light & Temperature

Grevillea ‘Bronze Rambler’ is a big sun-lover, and prefers to be in full sun, though thankfully, as a low-growing shrub, it does actually cope quite well with some afternoon shade, making it a useful plant for understory planting around the base of trees, or near fences, where it can come with slightly less sunlight than most grevillea species.

Caring for Grevillea ‘Bronze Rambler’

Grevillea ‘Bronze Rambler’ doesn’t take much care once established. In very, very dry summers, you can support continued flowering with a little bit of extra water (a bucket per week in summer is sufficient). 

The aim with these grevilleas is to try to encourage year-round flowering. While they do naturally flower all year round, they will usually put their efforts into a big winter and spring display, followed by a weak summer and autumn bloom. 

To boost flowering, increase watering and feed with phosphorus-rich fertiliser in later spring to encourage a second flush. In very dry conditions where dry winter soil is likely, add a layer of basic mulch to lock in moisture (spent compost is fine for this, as it’s for moisture, not nutrients).

Grevillea ‘Bronze Rambler’ Pests and Diseases

Grevillea ‘Bronze Rambler’ is more susceptible to sooty mould and fungal problems than most grevilleas, largely because their growth is dense and close to the ground, where humidity can be higher during wet summers. 

Ensure you plant your grevillea on well-drained soil to avoid these simple problems, and improve drainage where possible when you notice signs of fungal infections.
