It is one of the most attractive plants for arid areas because of its billowing crown and knobby trunk. Beautiful olive trees are a great addition to a yard's landscaping. This olive tree has several trunks and gorgeous gray-green and silver-colored leaves. Install landscape lights in and around the Olea europaea olive tree to show off its beauty. The evergreen Manzanillo Olive loves deep rich soil but can survive poor, rocky, shallow soils as well, so feel free to plant Olea europaea in a range of landscape designs.
