Echinocereus coccineus is a clumping cactus that forms large colonies of up to 100 thick stems on each plant at maturity. The stems are semi-erect, dark green, up to 16 inches (40 cm) tall, and up to 2 inches (5 cm) in diameter. They can vary from almost spineless to wildly and densely spined. The spines are yellowish and turn grey after some years. Flowers are up to 3.2 inches (8 cm) long, up to 1.2 inches (3 cm) in diameter, and appear in spring. Flower colors range from near orange, scarlet, and pink to deep crimson shades.
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 successfully grow other globular cacti, you can most likely grow Echinocereus well. One of the key factors in success 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, carefully remove it from its pot and knock away any clumped soil. These plants tend to be shallow-rooted with weak root systems, so take care not to damage their roots.
