Origin and Habitat: Hills Between General Cepeda and La Rosa, foot-hills and adjacent areas up to the Sierra de Paila. The type locality is near Saltillo, Coah. Mexico.
Habitat: The plants grow among the shrubs and grasses or hidden amid fragmented stones of brown lime-rocks on fine sediment. They are almost exlusively found on the north side of small hill-formations elevating not more than 10 meters from the plain. The habitat is located 1.100-1450 meters above sea-level and wind is blowing most the time. Camouflage: The fine spines of this species are an optical artifice supporting the grass-mimicry to the surroundings.

Description: Small growing variety of the species when living in open fields
Stem: Small 10 and 12 centimetres tall, diameter up to 6-8 centimetres (or more in cultivation) with usually less and smaller white dots like in the type, never red-brown dots.
Spines: Thin and twisted covering the body.
Flowers: Magnificent up to a diameter of 10 centimetres which cover the whole body like an umbrella.
Blooming time: From April to October, they have the ability to flower as very young plants (At the age of three years)
Fruits: The variety minor has most seed-rich fruit of all Astrophytums.
Remarks: Astrophytum capricorneSN|3564]]SN|3564]] and its varieties are very variable in their habit even in small areas. And it is understandable that today we often have problems to decide to which population plants belong.

Cultivation and Propagation: It is a popular summer-growing species of relatively easy cultivation.
Growth rate: Slow-growing.
Soil: Grow it in an open standard, sandy-gritty cactus compost and provide a very good drainage.
Exposure: It is suited for sunny-brightly exposure, but can tolerate light shade. However it will do its best with lots of sun and become stressed with inadequate light which could result in poor growth and unnatural shape. It has a good heat tolerance.
Watering: Water regularly (about once a week) during the growing season and keep it completely dry during winter or when night temperatures remain below 10° C. Water it less than average if in bigger pots.
Fertilization: Feed them once during the growing season with a fertilizer specifically formulated for cactus and succulents (high potash fertilizer with a dilute low nitrogen), including all micro nutrients and trace elements diluted to ½ the strength recommended on the label. They thrive in poor soils and need a limited supplies of fertilizer to avoid the plants developing excess vegetation, which is easily attacked by fungal diseases.
Special need: It is suited for airy exposures. Provide very good ventilation. Nearly all problems occur as a result of overwatering and poor ventilation, especially when weather conditions are dull and cool or very humid. ere.
Hardiness: It likes warmth (recommended minimum winter temperature 5° C) But plants kept perfectly dry can easily survive to light frost (it is reported hardy to -7° C for brief periods).
Pests & diseases: These cacti may be attractive to a variety of insects, but plants in good condition should be nearly pest-free, particularly if they are grown in a mineral potting-mix, with good exposure and ventilation. Nonetheless, there are several pests to watch for:
- Red spiders: Red spiders may be effectively rubbed up by misting the plants from above.
- Mealy bugs: Mealy bugs occasionally develop aerial into the new leaves and flowers with disfiguring results, but the worst types develop underground on the roots and are invisible except by their effects.
- Scales, thrips and aphids: These insects are rarely a problem.
- Rot: Rot is only a minor problem if the plants are watered and “aired” correctly. If they are not, fungicides won't help all that much.
Propagation: It can be propagated easily from seed (seldom produces offsets). The seeds can be sown in pots of fine, well-drained sandy soil, any time during the spring when temperatures are warm. Cover the seeds with a fine layer of grit and water from below with a fungicide to prevent damping off. For the 1-2 weeks cover the pots with a sheet of glass/clear perspex to keep the humidity levels high. Remove the glass and replace it with light shade-cloth and mist once or twice a day for the next two weeks after which most seeds should have germinated. From then on mistings can be reduced to every second and then every third day as the little plants grow. The seedlings should not be disturbed until they are well rooted after which they can be planted separately in small pots. Sometimes it is grafted to avoid root rot problems as plants grafted on an hardy stock are easy to grow and no special skill is required.
