Olive Trees: A Field Guide
Olive trees are “patient trees which will live in the stoniest ground,” as the British landscape architect Russell Page summed up the situation. What more do you need to know to know that you want one of these ancient, graceful trees?
You can have one, too, if you live in a warm, sunny climate that mimics the Mediterranean regions where Olea europaea is most at home (USDA growing zones 8 to 11, depending on the cultivar). Olive trees life exceptionally long lives—1,500 years is nothing to them—and will become more characterful as centuries pass and their thicken and spread like gnarly knuckles across the landscape.
An olive tree (or two, if your garden is large and you would like an echo) is best planted as a specimen tree—and focal point. “I have very often gardened in Mediterranean places where old olive trees gave the basic note with their gnarled and twisted trunks and silvery-green, sun-flecked foliage,” Page wrote in his 1962 book The Education of a Gardener.
