Origin
Echinocactus texensis is native to Mexico (Chihuahua, Coahuila, Durango, Nuevo León, Zacatecas, and Tamaulipas) and the United States (southeastern New Mexico, Texas, and Oklahoma).
Description
Echinocactus texensis is a small cactus with a usually solitary stem with 13 to 27 very prominent ribs lined with wooly areoles that bear clusters of stout, mostly decurved spines. The stem is flat-topped and hemispheric when mature but usually deep-seated, reaching up to 8 inches (20 cm) in height and up to 12 inches (30 cm) in diameter. The spines are flattened to nearly cylindrical and range from pale tan, pink, and reddish to gray. Each areole bears 5 to 7 radial spines and one central spine.
The flowers have bright rose-pink to pale silvery-pink inner tepals, orange to red near the center, and pink to pinkish-white stigma lobes. They appear in late spring and can reach up to 2.4 inches (6 cm) in length and diameter. The fruits are scarlet or crimson, spheric to ovoid, up to 2 inches (5 cm) long and up to 1.6 inches (4 cm) in diameter, with tiny black seeds inside.
Hardiness
USDA hardiness zones 9a to 11b: from 20 °F (−6.7 °C) to 50 °F (+10 °C).
How to Grow and Care
Overall, these are beautiful cacti for dish gardens or indoor displays. Their collection is especially attractive, as they look like a collection of balls tossed upon the ground. It's critical, however, to never let these cacti be exposed to prolonged periods in water or even very high humidity. They will suffer from rot in the presence of humidity. In addition, Echinocactus are vulnerable to pests, including aphids, mealy bugs, scale, and whitefly. Identify the infestation as early as possible and treat it with the leave toxic option.
It's best to repot at the beginning of the growing season or summer. To repot a cactus, ensure the soil is dry before repotting, then gently remove the pot. Knock away the old soil from the roots, removing any rotted or dead roots.
