Agave schottii Engelm.
Schott's Agave, Schott's Century Plant
Agave geminiflora var. sonorae, Agave schottii var. schottii
This species is native to the United States (Arizona and New Mexico) and Mexico (Chihuahua, Sonora, and Baja California). It occurs in gravelly to rocky places, mostly in desert scrub, grasslands, juniper, and oak woodlands at elevations between 2,950 and 6,550 feet (900 and 2,000 m).
Agave schottii is a succulent plant that forms stemless rosettes of linear yellowish green leaves with or without conspicuous bud-prints on both surfaces, filiferous margins, and a brown or grayish apical spine. The rosettes grow up to 2 feet (60 cm) tall and 4 feet (1.2 m) in diameter, freely suckering to form a large clump. Leaves are mostly erect, widest near the base, up to 20 inches (50 cm) long, and up to 1 inch (2.5 cm) wide. Fibers are white, erect to spreading, sparse, filiform, and brittle. Flowers are yellow, funnelform, about 0.5 inches (1.1 cm) long, 0.3 inches (0.8 cm) in diameter, and appear solitary or in clusters of up to 6 on spicate or subspicate inflorescences from late spring to late summer. Fruits are obovoid, up to 0.9 inches (2.2 cm) long capsules with black seeds.
The specific epithet "schottii (SHOT-ee-eye)" honors Arthur Carl Victor Schott (1814–1875), a German-American artist, topographical engineer, cartographer, botanist, ethnographer, and geologist.
How to Grow and Care for Agave schottii
Light: Like all Agaves, this plant requires full sun to partial shade. If growing A. schottii indoors, choose a bright, sunny window with as much sun as possible. From spring to fall, it loves going outside.
Soil: A. schottii will tolerate most soils as long as they have good drainage, but its preference is sandy or rocky soil.
Temperature: During the growing season, it likes warm temperatures, while in winter, when resting, this succulent enjoys cooler temperatures. A. schottii can withstand temperatures as low as 20 °F (-6.7 °C). USDA Plant Hardiness Zones 9a to 11b, 20 to 50 °F (-6.7 to 10 °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. schottii a small amount of fertilizer in the spring during the first two years. After that, established plants seem to take care of themselves.
Repotting: If you notice your A. schottii becoming pot-bound, repot it with fresh soil in a new pot that is just slightly larger than the old one. Give the plant a week or so to readjust before you water it again.
Propagation: Since it can take years to produce seeds, A. schottii is usually propagated by offsets. The best time to remove the offsets is in spring and summer. Sow the seeds in spring.
