Persea–commonly called avocado–is a tropical tree that grows to greater than 60 feet (18m) tall. It also is grown as a foliage plant indoors.
Persea is a rapid grower in tropical and subtropical regions. It produces dense shade. Persea is an evergreen that drops leaves throughout the year. Persea terminal shoots can be trimmed or pinched to shape the plant. Persea grows well in containers and can be moved indoors if temperatures turn cold. For best growth, the minimum temperature should not fall below 55° to 60° (13°-16°C).
There are three types (called “races”) of Persea americana, edible avocado, Mexican, Guatemalan, and West Indian; Guatemalan is most hardy and West Indian most tropical. The Mexican type produces the largest fruit.
Persea is a genus of about 150 tropical trees, many grow to taller than 60 feet in their native habitat. Persea is native to Southeast Asia, Micronesia, and tropical and subtropical North and South America.
