Origin of Olives in South Africa
South Africa already had an olive tree when the Europeans arrived — just not the one that makes oil. The story of how the Mediterranean olive was grafted onto an African one is the most interesting thing about Cape olive growing.
The Western Cape has a Mediterranean climate — wet winters, hot dry summers — which makes it one of the few places outside the Mediterranean basin where olives feel genuinely at home rather than merely tolerated. But the industry that grows there today is barely a century old, and it was built on a piece of botanical luck that most accounts skip past.
South Africa has its own native olive. Olea europaea subspecies cuspidata, the wild olive that Afrikaans calls olienhout, grows across the country’s hills and river courses. Its fruit is small, bitter and of no commercial use whatever. Its root system, however, is superbly adapted to South African soils and drought — and it is close enough kin to the Mediterranean olive to accept a graft.
A diary note, then two centuries of nothing much
The written record starts with Jan van Riebeeck, the Dutch East India Company commander at the Cape, who noted in his journal in 1661 that olive trees were growing successfully on the farm Boschheuvel. That is a genuine first — but it led nowhere in particular. The Cape’s colonial agriculture went to wheat, wine and fruit. Olives remained an ornamental curiosity and an occasional garden tree for the best part of two hundred and fifty years.
What was missing was not climate. It was know-how: which cultivars to plant, how to graft them, how to cure the fruit, how to mill oil that anyone would want to buy. That arrived, as it so often did in the New World olive story, with an Italian.
The nurseryman from Nervi
Ferdinando Costa trained as an agriculturist at the Saint Ilario college near Genoa and came to the Cape in the early 1900s to join his brother, who was running a nursery at Wynberg. He set up on his own at Newlands, and there did the thing that mattered: he obtained scion wood of good Italian cultivars from his former college contacts and grafted them onto the indigenous wild olive growing all over the Boland foothills.
That is the whole trick. Instead of importing whole trees and hoping they would establish, he married Mediterranean fruiting wood to African roots already suited to the ground. He supplemented the Italian material with varieties from Australia and California — a reminder that the olive’s global spread was a network, not a single line out of Europe. Having raised many thousands of trees, he bought a farm on a gentle slope at Huguenot, near Paarl, in the 1920s and named it after Nervi, the seaside town near Genoa where he was born. He produced oil there in the 1930s on a hydraulic press imported from Italy, and is generally credited as the father of the South African olive industry.

What the Cape industry is now
South Africa remains a small producer by world standards — its whole annual output would barely register against a single Spanish province — and that is precisely its strategy. It cannot compete on volume, so it competes on freshness, on estate identity and on a domestic and regional market that will pay for provenance. The country’s producers built a voluntary certification scheme with chemistry and taste-panel requirements plus traceability, for the same reason the Australians did: a small producing country selling against cheap imports gains nothing from loose standards.
- Buy South African oil in the southern winter and spring, soon after the March-to-May harvest.
- Look for the local certification seal — it verifies both quality and that the oil is genuinely South African.
- Expect a robust style: many Cape oils are picked green and lean peppery and bitter rather than mild.
- The counter-season is the point. Cape oil is at its freshest when northern-hemisphere bottles are approaching a year old.
- Do not confuse the wild olive with the crop — olienhout is a fine indigenous tree, but it is a rootstock and a timber, not a fruit.
Olives in South Africa: common questions
Are olives native to South Africa?
A wild olive is: Olea europaea subsp. cuspidata, known as olienhout. Its fruit has no commercial value, but it is closely related enough to the Mediterranean olive to serve as excellent drought-tolerant rootstock.
When were olives first grown at the Cape?
The first recorded planting dates to 1661, when Jan van Riebeeck noted olive trees growing at the farm Boschheuvel. Commercial cultivation did not begin for roughly another two and a half centuries.
Who started the South African olive industry?
Ferdinando Costa, an Italian-trained agriculturist who grafted good Mediterranean cultivars onto indigenous wild olive rootstock and established a farm near Paarl, is generally regarded as its founder.
When is the South African olive harvest?
Roughly March to May — autumn in the southern hemisphere — which puts fresh Cape oil on the shelf as northern-hemisphere oil is nearing the end of its best window.
Is South Africa a significant olive oil producer?
Not by volume; its output is small on a world scale. It competes on freshness, estate identity, certification and a domestic market willing to pay for provenance.
The grafting detail is the one worth keeping. Every olive region outside the Mediterranean had to solve the same problem — imported trees sulking in unfamiliar ground — and the Cape solved it by using what was already growing on the hillsides. It is also a useful corrective to the romantic story of the olive spreading outward from Greece in a single graceful arc. Costa took wood from Italy, but also from Australia and California, because by 1900 the olive was already a global crop moving in every direction at once. The Mediterranean is the olive’s birthplace, not its address.
