Agave durangensis

Also called American Aloe Plant or Century Plant.
This specie is native to Mexico, where it is found above 1,500 m in Durango.
It is an evergreen succulent that forms large rosettes (1,8 m in diameter) with long leaves 90 cm.
Light: Like all Agaves, this plant requires full sun to partial shade. If you are growing it indoors, choose a bright, sunny window with as much sun as possible. From spring to fall, it loves going outside.
Soil: A. durangensis will tolerate most soils as long as they have good drainage, but its preference is sandy or rocky soil.
Hardiness: During the growing season, it likes warm temperatures, while in winter, when resting, this succulent enjoys cooler temperatures. It can withstand temperatures as low as -7°C.
Watering: from spring to fall, water thoroughly when the soil becomes dry. In winter, water sparingly about once a month. Plants in containers require more frequent watering than those in the ground.
Fertilizing: give your A. durangensis a small amount of fertilizer in the spring during the first two years. Established plants seem to take care of themselves.
Repotting: Repot in a pot that is just slightly larger than the old one. Give the plant a week or so to readjust before you water it again.
