AG11 Jarilla Mts. These cacti can clump to form mounds of almost mythic proportions. The birdie-flowers are red with rounded petal tips, they are real traffic-stoppers.
Origin and Habitat: Southwestern USA (Arizona, Texas, New Mexico, Colorado, Utah, Nevada, California) and Mexico (Baja California, Sonora, Coahuila, Chihuahua). Echinocereus coccineusSN|7140]]SN|7140]] has a very large extent of occurrence, is abundant and common, and there are no major threats.
TL: New Mexico, Wolf Creek, Wislizenus,24 June 1846 (MO).
Altitude range: (150-)1500-2800(-3000) metres above sea level.
Habitat: Chihuahuan Desert, desert scrub (chaparral), desert grasslands, bajadas, Great Plains grasslands, pinyon-juniper and oak woodlands, mountain forest, forest clearings. It grows on rocky outcroppings and cliffs, on loamy, humus, mineral soil and and also in igneous, metamorphic, and limestone substrates, with humus, often in the partial-shade of oak and pine-oak woodlands and mixed conifer forest. It is pollinated by hummingbirds and halictid bees, and it has both hermaphroditic and dimorphic populations.

Description: Usually clumping, Echinocereus coccineusSN|8493]]SN|7140]] forms large colonies of as many as 50-100 (500)-thick stems on each plant at maturity. Stems can vary from almost spineless to wildly and densely spined. Two subspecies are recognized, the nominate and Echinocereus coccineus subs. paucispinusSN|7140]]SN|8493]] (Engelm.) W.Blum. Mich.Lange & Rutow.
Stems: Semi-erect, dark green, from 8 cm to 40 cm tall, 5 cm in diameter.
Ribs: 8 to 11.
Spines: Mostly undifferentiated between radials and centrals. Spines are yellowish and turn grey after a number of years.
Central spines: 0 to 4 , up to 7.5 cm long.
Radial spines:* 5-20.
Flowers: Hummingbird-attracting, colour ranges from near orange, scarlet , and pink to deep crimson shades, with rounded petal tips length and width averaged 80 mm and 30 mm, respectively, stigma with 7 or 8 lobes.
Blooming season: Peak flowering comes from late April to June on mature clumps. Fruiting 2-3 months after flowering.
Subspecies, varieties, forms and cultivars of plants belonging to the Echinocereus coccineus group
- Echinocereus arizonicus subs. matudae (Bravo) Rutow: has larger stem, up to 50 cm tall, and 12 cm in diameter, a reduced number of ribs with fewer short, thick spines. Distribution: Mexico, Chihuahua.
- Echinocereus coccineus Engelm. in Wisliz.: It has stems that are 2,5 to 5 cm thick, with 8 to 11 ribs. The spines are not differentiable between centrals & radials. There are 0 to 4 central spines and 5 to 20 radial spines per areole. The red-orange flower is 7-8 cm across, and the stigma has 7 or 8 lobes.
- Echinocereus coccineus var. arizonicus (Rose ex Orcutt) D.J.Ferguson
- Echinocereus coccineus var. gurneyi (L.D.Benson) S.Brack & K.D.Heil: Stems darker green in color compared to the other varieties, and 10 cm thick. The flowers are Orangish-red. This variety is often included into the 'coccineus' subspecies. It looks like coccineus, but is very clustering!
- Echinocereus coccineus subs. paucispinus (Engelm.) W.Blum, Mich.Lange & Rutow in W.Blum et al.: It has stems that are about 6 cm thick, with 5 to 8 acute narrowly furrowed ribs that have areoles that are spa ced 0,5 to 1 cm apart. It has 0 or 1 central spine, 1.4 inches long, and 3 to 6 radial spines that are curved and straight. The flower is red with a hint of orange & shaped like a funnel about 5 cm long, having 7 lobes of the stigma.
- Echinocereus coccineus var. rosei (Wooton & Standl.) A.D.Zimmerman: This plant has relatively long, white wool in the areoles of the ovary and fruit. Flowers scarlet (pink and orange flowered plants are also reported)
- Echinocereus roemeri Engelm. ex F.Haage
Notes: Female and male flowers: Echinocereus coccineusSN|7140]]SN|7140]] is a cactus with both hermaphroditic (bisexual) and dioecious (male and female) forms of flowers in different plants. Male flowesr show pollen-filled anthers surrounding the base of the stigma lobes. Functional female flowers from different plants show reduced filaments and empty anther sacs held below the stigma lobes.
The flowers appear specialized in hummingbirds, but are also pollinated by bees. They are huge and highly rewarding, and daily nectar production averages 30 mg sugar per flower. This set of traits represents a syndrome rare among hummingbird flowers, in which the flower fits the head rather than just the bill, and birds are well rewarded for a risky or inconvenient visit.

It makes great potted specimens.
Soil: Use a mineral well permeable soil with little organic matter (peat, humus). It grows in limestone areas of Texas (Big Bend area) and adjacent areas of Mexico, so will probably benefit from extra calcium in its soil.
Growth rate: It grows well, though slowly, but it possible to increase the speed of growth to some extent by providing adequate amount of water, warmth, and a liquid fertilizer diluted half strength during the active growing season, but it’s susceptible to rotting if too wet. Most plants will offset readily, and clumps can be produced in a few years.
Soil: It needs a very porous, slightly acidic potting medium (add pumice, vulcanite, and perlite). Outdoors it does well on poor, rocky soils.
Exposure: It likes a sunny position also blasting sun in summer. If grown indoor provide 4 to 6 hours, or more, direct morning or afternoon sun.
Watering: It is sensitive to overwatering (rot prone) needs a very good drainage to avoid rotting, but requires more moisture than true desert cacti to grow and produce flowers.
Hardiness: It its natural environment it is very cold resistant from -10° to -25° C (depending on clones) or less for short periods of time. It can be grown outdoors in Mediterranean warm-temperate climates, But for safe cultivations needs anyway to kept above 5 °C and dry in winter. But it can tolerate temperatures down to -5° C (or even less) for very short periods if very dry and ventilated. During winter month, put them in a cool luminous place and encourage them to enter winter dormancy by withholding water and fertiliser over the winter as they will etiolate, or become thin, due to lower levels of light.
Maintenance: Repot every two years. Needs lots and lots of space to grow, use large shallow container or bowl filled with very porous compost. It like pots with generous drain holes.
Pest & diseases: They are susceptible to fungal diseases if overwatered, but are not nearly as sensitive as many other cacti, especially in warm weather. If kept damp through cold periods, they will invariably suffer.
Garden uses: It is a fine plant for a rock garden or container, contrasts well with agaves, yuccas, and low-growing flowering plants.
Grafting stock: The taller fast-growing forms of Echinocereus coccineusSN|7140]]SN|7140]] and of Echinocereus triglochidiatusSN|7140]]SN|10576]] are highly recommended stocks for grafting cold hardy type cactus species. These can be used as cold hardy type stocks for almost all types of cactus, while still retaining the original natural grown look to the scion.
Edible uses: The fruit can be consumed fresh or preserved.
Propagation: Cutting as it branches freely from the base; Also can be grown from seeds. The seeds may be germinated and grown in containers. Their main requirements consist of high humidity levels, free-draining soil mix, and enough water, light, and nutrition.
