Agave sisalana is an evergreen, flowering, succulent, rosette-forming perennial shrub. plants, consist of a rosette of sword-shaped leaves about 1.5–2 meters (4.9–6.6 ft) tall. Young leaves may have a few minute teeth along their margins, but lose them as they mature.
The sisal plant has typically produced 200–250 commercially usable leaves. Each leaf contains an average of around 1000 fibres. The fibres account for only about 4% of the plant by weight. Sisal is considered a plant of the tropics and subtropics since production benefits from temperatures above 25 degrees Celsius and sunshine.
