Fruit pear-shaped, ± ovoid or globose, mostly 7–15 cm long, 5–7 cm or more diam., usually dark green skinned (can vary in shades of green to purple to black), pulp fleshy, oily, calyx not persistent; seed globose to ovoid, c. 30–40 mm diam.; sometimes fruit 5–7 cm long at end of season or on some naturalised plants.
A small to medium sized tree. It grows 8-10 m high. Trees can grow to 25 m high. The leaf stalk is 1.5-5 cm long. Leaves are entire, oval and 5-40 cm long. Flowers are greenish, small and on the ends of branches. Clusters of flowers may contain 200-300 flowers. Normally only 1-3 fruit develop from each cluster. The fruit is pear shaped or round. It can be 7-20 cm long. The fruit are greenish-yellow with some red coloration. The fruit has greenish yellow flesh and a large round seed. There are 3 named races-West Indian, Guatemalan and Mexican.

Environment

A subtropical plant. Trees grow from sea level up to 2250 m altitude in the tropics. It cannot stand water-logging. Branches are easily damaged by wind. It needs to be in a frost free location or where frosts are rare. West Indian varieties thrive in humid, tropical climates and freeze at or near O°C. Mexican types are native to dry subtropical plateaus and thrive in a Mediterranean climate. They are hardy-4 to-7° C. They are salt sensitive, has the smallest fruits and the thinnest skin. The best daytime temperature is 25-33°C. Guatemalan types are native to cool, high-altitude tropics and are hardy-1° to-3° C. It does best with neutral or slightly acid soil. West Indian avocadoes can stand some salinity. They need a well aerated soil. Growth is disrupted when soil temperatures are below 13°C. It needs high humidity at flowering and fruit set. It can grow in arid places. It grows in Miombo woodland in Africa. In Argentina it grows between 1,500-1,800 m above sea level. It suits hardiness zones 9-11. In Sichuan and Yunnan.

Usage

Persea americana is widely cultivated for its edible fruit and oil. Avocado oil is used in cooking and in the cosmetic industry. Avocado is an important commercial crop with many cultivars, 'Hass' being one of the most common varieties of fruit. The fruit has various nutritional and medicinal values (the health benefits of eating avocados are widely documented), and extracts are also obtained from the seed and leaves, e.g. see Yasir et al. (2010), Orhevba & Jinadu (2011), Ranade & Thiagarajan (2015), Noorul et al. (2016), Hurtado-Fernández et al. (2018), and references therein. See also Rodd (1996), Spencer (1997).                        Hass                          Shepard
More
The pulp of the fruit is eaten raw or cooked. It is eaten in salads, soups, sandwiches, spreads, ice cream, and also in tortillas and in wine. The fruit are mixed with sugar and water to make a drink. Oil is extracted from the flesh. It is used in salad dressing. The leaves can be used for tea sweetened with sugarcane juice. Toasted leaves are used to season stews and bean dishes. Caution: Some people are allergic.

Cultivation

Plants are often grown from seed. Seeds remain viable for 2-3 weeks. Fresh seed held at 25°C day to 15°C night will germinate in 3 weeks. It is best to propagate vegetatively. Tip cuttings, layers and grafts can be used. Because different types have pollen at different times of day, for best pollination a mixture of trees which have pollen and flowers receptive at different times gives bet fruit set. Although trees will grow in shade, they need sun for fruiting. The leaves do not rot easily and can accumulate under trees. Other plants cannot be grown under avocado trees.
