Description: It is a popular solitary or slowly clumping cactus, the standard form of it with flat globular, bluish green stems up to 6 cm, 5-7cm in diameter is very common in cultivation, while the crested form here described is very rare and sometime visible only in specialized collections.
Areoles: 5 to7 mm inch apart
Spines: To 7 pale yellowish spines.
Root: It has a strong taproot.
Flowers: Abundant pink or purple/red (rarely white) flowers, up to 6 cm in diameter.
Subspecies, varieties, forms and cultivars of plants belonging to the Echinocereus pulchellus group
- Echinocereus aguirrei Glass: Small Clumper that produces great pink flower (same as: Echinocereus pulchellus var. amoenus?).
- Echinocereus pulchellus (Mart.) C.F.Först. ex F.Seitz: (subsp. pulchellus) has stems that are 2,5-5 cm thick with 9 to 12 ribs and 3 to 7 inconspicuous spines per areole. The flowers are pink or white. Distribution: Oaxaca, Puebla, Hidalgo, and Queretaro.
- Echinocereus pulchellus subs. acanthosetus (S.Arias & U.Guzmán) N.P.Taylor: has stems that are 2 to 4cm thick with 9 ribs usually and 5 to 8 flailing hairlike spines. The flowers are magenta to white. Distribution: Oaxaca.
- Echinocereus pulchellus var. amoenus (A.Dietr.) H.P.Kelsey & Dayton: It has 15 cm stems, 10 to 14 ribs and on the young areoles it has 6 to 8 short spines with the lower spine being the longest. The older areoles are devoid of spines. The flowers are magenta.
- Echinocereus pulchellus f. cristatus: It is a nice crestes form with bluish green stems.
- Echinocereus pulchellus subs. sharpii (N.P.Taylor) N.P.Taylor: It has darker colored stems in comparison to the other subspecies. Bodies 2 to 6 cm thick with 11 to 17 ribs and 7 to 14 spines per areole. The flowers are magenta or more often white. Distribution: Nuevo Leon and San Luis Potosi.
- Echinocereus pulchellus subs. venustus W.Blum & W.Rischer: has low greyish-green body and pink flowers from the lower part of the body. Flower up to 30 mm long and 50-55 mm across. Distribution: San Luis Potosi City to Aguascalientes.
- Echinocereus pulchellus subs. weinbergii (Weing.) N.P.Taylor: It has stems that are 5 to 15 cm thick with 14 or 15 ribs and 8 to 11 spines per areole. It has pink diurnal flower. The petals are narrowly acute in shape. Distribution: Zacatecas.
Cultivation and Propagation: It is not too difficult in a greenhouse, although grows quite slowly. It is usually seen as a grafted plant but can grow on its own roots too.
Soil: Use a mineral well permeable soil with little organic matter (peat, humus).
Exposure: They need a good amount of light shade to full sun this help to keep the plants healthy, although slow growth.
Watering: Water sparingly from March till October (weekly during summertime, if the weather is sunny enough), with a little fertilizer added. Less or no water during cold winter months, or when night temperatures remain below 10° to prevent root loss. It is sensitive to overwatering (rot prone).
Fertilization: Feeding may not be necessary at all if the compost is fresh then, feed in summer only if the plant hasn't been repotted recently. Do not feed the plants from September onwards as this can cause lush growth which can be fatal during the darker cold months.
Hardiness: Keep perfectly dry in winter at temperatures from 5 to 15 degrees centigrade. (but it is relatively cold resistant and hardy to -5° C, or possibly colder for short periods) In the rest period no high atmospheric humidity!! (Temperature Zone: USDA 9-11)
Crested growth: Unlike 'monstrose' varieties of plants, where the variation from normal growth is due to genetic mutation, crested growth can occur on normal plants. Sometimes it's due to variances in light intensity, or damage, but generally the causes are unknown. A crested plant may have some areas growing normally, and a cresting plant that looks like a brain, may revert to normal growth for no apparent reason. If you have any of the crested part left you need to remove the normal growth and leave the crested part behind this will need to be done regularly.
Propagation: Grafting or cuttings. Plants are usually grafted onto column-shaped cacti but proved to be able to produce their own roots if degrafted. Cuttings will take root in a minimum temperature of 20° C (but better in hot weather). Cuttings of healthy shoots can be taken in the spring and summer. Cut the stem with a sharp, sterile knife, leave the cutting in a warm, dry place for a week or weeks (depending on how thick the cutting is) until a callus forms over the wound. Once the callus forms, the cutting may be inserted in a container filled with firmed cactus potting mix topped with a surface layer of coarse grit. They should be placed in the coarse grit only; this prevents the cut end from becoming too wet and allows the roots to penetrate the rich compost underneath. The cuttings should root in 2 to 6 weeks. Large crested piece must be placed on the soil surface without burying the plant base down in the soil.
