“Acebuche” is a wild olive tree, the wild form of the cultivated olive tree. Its scientific name is Olea europaea var. sylvestris. It is therefore the same species as the cultivated olive tree, but grows in the wild. In fact, if an olive grove is left uncultivated for a long period of time, the olive trees gradually revert to their wild form and develop many of its characteristics.
The wild olive tree typically grows as a shrub or bush. Compared with the cultivated olive tree, its stems are thicker and more robust, while its leaves are broader and have a more vivid, intense color.
The fruit of the wild olive tree is known in Spanish as an acebuchina. It is similar to an olive, but smaller. The amount of fruit produced by a wild olive tree is considerably lower than that produced by its cultivated relative.
In some areas, people make wild olive oil at home, as harvesting the fruit and producing the oil would not be commercially viable on a larger scale. Small home producers can occasionally be found on internet forums.
The wild olive tree is a characteristic part of the Mediterranean landscape and woodland, growing alongside holm oaks, carob trees and cork oaks. It can reach heights of up to 10 meters, although this is uncommon. It is more typically found growing as a shrub or bush. It can usually be recognized by its intense, dark green leaves.
Wild olive trees are extremely hardy, tough and resilient plants. Some specimens may even have thorns. Like cultivated olive trees, they are highly resistant to drought and can grow well in poor soils. However, just like their cultivated relatives, they do not thrive in cold conditions or excessive moisture.
They can grow in practically any area with a Mediterranean climate.
The first photograph shows a newly sprouted wild olive tree. It was taken in an area cleared during the construction of a road in a residential development on the Andalusian Mediterranean coast.
The second photograph shows a young wild olive tree growing right next to the newly sprouted one.
If you enjoy walking in the countryside, you have probably come across more than one wild olive tree. You just need to keep your eyes open.
Etymology
One possible origin of the word comes from Dioscorides, a Greek physician and botanist who is considered one of the forerunners of modern pharmacology.
Dioscorides referred to the wild olive tree as "zebbuj", while the Berbers called it "azzemur". The Spanish word acebuche is thought to have evolved from these terms.
