Origin
Echinocereus coccineus is native to the southwestern United States (California, Nevada, Utah, Arizona, Colorado, New Mexico, and Texas) and northeastern Mexico (Baja California, Sonora, Chihuahua and Coahuila).
Description
Echinocereus coccineus is a small cactus with erect, spherical to cylindrical, dark green stems with 5 to 20 ribs lined with clusters of long spines. The stems are loosely aggregated into clumps or tightly packed into rounded mounds. The stems are up to 16 inches (40 cm) tall and 6 inches (15 cm) in diameter. Spines are ashy white to gray, brown, yellowish, reddish, or black, often dark-tipped. They are up to 3.2 inches (8 cm) long. Each areole bears 1 to 18 radial and 0 to 6 central spines.
The long-lasting, showy flowers are funnel-shaped, up to 3.2 inches (8 cm) long, and up to 1.2 inches (3 cm) in diameter, and appear from late spring to early summer. They are crimson or scarlet, less often orange-red, rarely rose-pink, with or without a whitish or yellowish, sometimes pink central part. Fruits are greenish or yellowish to pinkish, bright red or brownish tinged, up to 1.6 inches (4 cm) in diameter, and contain a white pulp and black seeds.
Hardiness
USDA hardiness zones 9a to 11b: from 20 °F (−6.7 °C) to 50 °F (+10 °C).
How to Grow and Care
If you can grow other globular cacti, you can most likely grow Echinocereus well. One of the key success factors is avoiding any hint of wet soil. Because their root systems are weak, they are especially prone to root rot, eventually killing your plant. Otherwise, they thrive on a program of intense, bright light, slight water, and a steady diet of light fertilizer. These cacti are vulnerable to mealybugs and aphids.
Echinocereus are slow-growing cacti that should only need repotting every other year or so. You can prolong the time to repotting by removing plantlets and potting them up in their own pots. When repotting a cactus, remove it from its pot and remove any clumped soil. These plants tend to be shallow-rooted with weak root systems, so take care not to damage their roots.
