Description
Agave filifera is an eye-catching succulent that forms compact, stemless rosettes of dark green leaves with ornamental white bud imprints, striking white filaments along the margins and ending in a sharp gray terminal spine. The rosettes can grow up to 26 inches (65 cm) in diameter, producing offsets near the base. The leaves are lance-shaped and measure up to 16 inches (40 cm) long and 2 inches (5 cm) wide.
The bell-shaped flowers appear densely arranged on an erect, unbranched, bottlebrush-like inflorescence that can reach up to 8.2 feet (2.5 m) in height. They are yellowish-green at first, becoming reddish, and about 2 inches (5 cm) long.
Hardiness
USDA hardiness zones 9a to 11b: from 20 °F (−6.7 °C) to 50 °F (+10 °C).
How to Grow and Care
Agaves are not difficult plants to grow. They are slow-growing and dramatic and will even thrive on a bit of neglect. If you are the type of person who likes to fuss with houseplants and water a lot, Agave is probably not the plant for you. On the other hand, if you are the type of person who likes to set it and forget it, and you have a sunny window, Agave might be the way to go. Be aware that some large varieties will eventually outgrow your room (unless you have a large greenhouse), and Agave can be aggressive. They have irritating sap and sometimes very sharp thorns that can cause injuries to small children and even pets.
In general, Agaves do not need to be repotted every year. Most species commonly found in cultivation grow slowly and take long to outgrow their pot. It is also best to handle your plants as little as possible since they do not like to be disturbed. When repot, refresh the spent soil with a new potting mix and ensure the plant is firmly anchored in its pot. However, be careful not to pot the Agave too deep, as that will encourage stem rot during the growing season.
