Arbequina Olive
A Spanish variety of fruiting olive, this attractive, small evergreen tree is self fruitful and early to ripen its small, green fruits. It is prized as an ornamental plant for its rugged good health, strappy grey-green leaves, clusters of tiny creamy blossoms in late spring, and the hard, green fruits that can ripen in long-summer areas with hot weather.
Fruit will set in most full-sun locations; if growing in a pot, you can bring it inside if fruits do not quite ripen before cold weather sets in. Arbequina is one of the most cold-tolerant fruiting varieties, withstanding temps down to 10F. Grows in USDA zones 8-10.
