Wilson Olive
Olea europaea 'Wilson'
Olive trees have been valued since the time of the Roman Empire with their attractive and interesting trunk formations. The olives can be processed as green olives (unripe) or black olives (ripe). Ripe olives can be pressed to extract oil, unprocessed olives are not edible. Uncollected olives may stain pavement, and can create a mess. Olive trees can be sprayed to prevent blooming and then fruiting. Many people are allergic to olive pollen (or contact with the leaves) and non-sterile variety are forbidden to sell in several locations of the western USA including the Las Vegas valley. There are hybrid varieties available that produce little or no pollen which may be planted without violating local codes.
