Description
Echinocereus pentalophus is a cactus that forms multiple finger-like green to reddish-purple stems with 4 to 6 ribs and 4 to 8 spines per areole. The stems are up to 3.3 feet (1 m) long and 1 inch (2.5 cm) in diameter. Spines are stiff and white or yellowish. One of the spines is a little longer and more central. This cactus produces many brilliant pink or magenta flowers with a white or yellow throat. They are funnel-shaped, up to 6 inches (15 cm) in diameter, and appear in spring. Fruits are green with 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 successfully grow other globular cactus, you can most likely grow Echinocereus well. One of the key factors in success with these 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, little 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.
