The Zutano avocado resembles the fuerte avocado with its pear shape and thin, glossy green skin, which remains green even when ripe, however its flesh is not as creamy or as rich in flavor. It has low oil but high water content, resulting in a slightly watery flavor, and has pale green flesh with a fibrous texture. Its mild flavor and problematic peeling makes it less desirable than other avocado varieties. The Zutano avocado tree grows upright, with a rounded shape and spreading branches, reaching heights of thirty to forty feet. It has oval dark green leaves with a glossy sheen, and its small flowers are greenish-white in color and they bear in clusters at the branch tips. The Zutano avocado tree produces heavily and is more tolerant of cold weather than other cultivars. The fruits mature to about six inches in length, averaging six to fourteen ounces in weight, and are harvested from mid-autumn to late winter. The avocados must reach full maturity, taking about six months, before they are harvested. However, unlike most fruit, avocados will not ripen on the tree, allowing growers to essentially use the avocado trees as a warehouse for storing fruit for months after maturity.
