H. texensis is, of course, named for the State of Texas where it is widely distributed and deserves to be more popular in cultivation

It is a round-shaped barrel with numerous flat ribs that grows very low to the ground with short but very thick pink o grey spines that can live for decades.
 

Description: Solitary when young, very rarely slowly clustering in age, Stems pale grey-green (desert populations) to grass green (eastern populations) with numerous ribs , above-ground portion flat-topped, hemispheric in old age but usually deep-seated, flush with soil surface 30 cm in diameter, 20 cm high
Spines small but strong pale tan, pink, reddish to grey, terete to flattened, annulated, not hiding stem surfaces. Radial (5-)6-7 per per areole, mostly decurved, Central 1 porrect and straight.
Flowers: 5-6 × 5-6 cm. Flowers range from white thru rose-pink to pale silvery-pink, with red throats in late spring and can appear on plants around 10cm in diameter. Fruits: scarlet or crimson, spheric to ovoid, 15-50 × 15-40 mm, fleshy,

Note: Desert populations of H. texensis, unlike the eastern plants, have longer central spines that project stiffly outward .

Synonyms:

• Homalocephala texensis (Hopffer) Britton & Rose
• Echinocactus lindheimeri

Common Names include:

• Horse Crippler (For the heavily spines that lies low to the ground, a hazard to horses, hence the name)
• Candy Cactus (For the edible and tasty red fruit. The plant is used to make a candy)
• Devil’s Pin Cushion

Origin:  This species is widespread and common in Texas, southeastern New Mexico, and Olkahoma (USA). It occurs also in northeastern Mexico (Coahuila, southern Nuevo León, Durango Tamaulipas)

Habitat and ecology: Chihuahuan Desert, grasslands, openings in oak woodlands, Tamaulipan thorn scrub, on deep soils, saline flats, low limestone hills or  limy gravel above Permian red dirt. 0-1400 m; It is a very hardy cactus that grows hidden in the grass. A dense cover of ephemeral herbs or shallow blanket of snow can hide this species completely from view.

Cultivation: H. texesis will do its best with lots of sun, it becomes stressed with inadequate light which could result in weak spines, poor health or even death. It does well with cool winter time temperatures and will tolerate temperatures down below -18°C or less if the roots are kept dry. This variety stores water in the parts of the plant which are above the soil leaving the root system small enough to fit into a proportionally sized flower pot. Needs well drained soil. It flowers easily as a house plant, but results will depend on a variety of growing conditions.
