Description: Echinocereus stramineusSN|7775]]SN|7817]] is a clumping cactus, forming large, compact colonies with 100 or more stems (occasionally up to 500 heads). These larger clumps are rounded, often 60-90 cm across and nearly as high.
Stem: Each head 10-30 cm long, 3-10 cm in diameter.
Ribs: 10 to 13 sinuous with fairly deep furrows between them.
Areoles: 8 to 25 mm apart.
Spines: 1 to 4 central spines, up to 9 cm long; 7-14 radials, up to 3 cm long. They vary from shortly - and frankly spined to long - and dense spined and from brightly white/ yellowish until dark red and black colours of spination.
Flowers: Abundant large bright pink to purple-red flowers in late spring, up to 12.5 cm diameter, 8-12 cm long, They are dark red (or rarely gold & green) at the base, fading to rose at the tips. The inner petals are toothed. The 10–15 outer petals have pink edges
Fruits: Dark red edible and delicious (tastes similar to strawberries just like Echinocereus engelmannii & Echinocereus cinerascensSN|7817]]SN|7775]] do), 5 cm in diameter.
Subspecies, varieties, forms and cultivars of plants belonging to the Echinocereus stramineus 2 group
- Echinocereus conglomeratus C.F.Först. ex K.Schum.: has smaller, more open flowers, smaller fruit, higher rib number and glassy white spines. Distribution: has a southern distribution area in Mexico (Nuevo Leon, Coahuila, and Zacatecas).
- Echinocereus stramineus (Engelm.) Engelm. ex Rümpler: (subsp. stramineus) is the most abundant in the southwestern US.
- Echinocereus stramineus subs. occidentalis (N.P.Taylor) N.P.Taylor: It is found only in the wild in Durango Mexico, and blooms a month later than the 'stramineus' subspecies.

Echinocereus stramineus Photo by: Cactus Art - SB1038 San Pedro, Coah. MX (form with very dense white spines ) The plants of this species are densely covered with many thin spines that give them a straw-like appearance. They vary from shortly - and frankly spined to long - and dense spined and from brightly white until dark colours of spination. Photo by: Valentino Vallicelli Echinocereus stramineus Photo by: Cactus Art Echinocereus stramineus Photo by: Cactus Art Cultivation and Propagation: Rot easily it is sensitive to overwatering (rot prone) needs a very good drainage to avoid rotting, Keep drier and cool in winter. Need full sun. Very cold resistant above approx -12C or less for short periods of time.
Uses: The Indians have known for a very long time that the Strawberry Cactus or Pitaya (Echinocereus stramineus) is good to eat, and modern science employs the fruit in the treatment of diabetes.
Propagation: Cutting as it produces abundant suckers. Also can be grown from seeds.
