Persea americana
Avocado (Persea americana; also avocado; alligator pear; aguacate) is a Lauraceae fruit plant grown for its berry. This page treats the accepted species name as canonical and uses the common name as a navigational alias.
| Avocado (Persea americana ) | |
|---|---|
| Scientific name | Persea americana |
| Genus | Persea |
| Family | Lauraceae |
| Order | Laurales |
| Fruit type | Berry |
| Growth form | Evergreen tree |
| Climate and hardiness | Tropical to subtropical tree with race-dependent cold tolerance |
| Mature height | 5–20 m; maintained smaller by pruning |
| Mature width | 5–15 m |
| Soil | Deep, aerated, freely drained soil; very sensitive to root-zone saturation |
| Water | Regular moisture with excellent drainage; drought and waterlogging both reduce performance |
| Sun | Full sun; young trees appreciate shelter from wind and heat extremes |
| Germination | 2–8 weeks from fresh seed; seedlings do not reproduce named varieties |
| Years to fruit | 2–4 years grafted; 5–10 years from seed |
| Pollination | Flowers are type A or B; compatible flowering types nearby can improve set |
| Harvest | Season varies by cultivar and climate; fruit can mature over a long window |
Identification and description
Avocado is a highly variable evergreen fruit tree divided horticulturally into Mexican, Guatemalan, and West Indian ecological races and their hybrids. The fruit is a single-seeded berry with oily flesh.
The accepted genus, family, and order are Persea, Lauraceae, and Laurales. Common names may cover related taxa; check the scientific name before transferring cultivation advice.
Growing
Natural habitats range from cool highland forests to warm lowland tropics, so rootstock and race matter as much as the species name. The key site requirement is oxygenated soil. Plant on mounds or raised ground where drainage is marginal, and protect shallow roots from heat and cultivation.
Soil
Deep, aerated, freely drained soil; very sensitive to root-zone saturation.
Sun and humidity
Full sun; young trees appreciate shelter from wind and heat extremes. Native habitat and airflow matter as much as light intensity; avoid enclosing humid foliage without ventilation.
Seasonal changes
Avocado habitats range from seasonally dry uplands to humid lowlands. Flowering follows local temperature and moisture patterns, while harvest maturity can extend for months because many cultivars hold fruit on the tree. Reduce irrigation only enough to avoid saturation; drought during fruit set can cause drop.
Propagation
Commercial trees are grafted or budded onto selected rootstocks. Fresh seeds germinate readily and make useful rootstocks, but seedling fruit quality and maturity are unpredictable.
Flowering, fruiting, and harvest
Season varies by cultivar and climate; fruit can mature over a long window. Flowering and ripening are strongly affected by latitude, cultivar, rootstock, rainfall, and temperature; local records are more useful than a single universal calendar.
Fruit and uses
Fresh fruit is eaten sliced, mashed, or in sauces. It is also used in chilled soups, spreads, dressings, and oil production. The flesh is nutrient-dense and highly perishable once cut.
