Origin and Habitat: Maihueniopsis conoideaSN|7342]]SN|7369]] is only known from the type locality in Baños de Puritama, Prov. Antofagasta, Chile, and adjacent areas, its extent of occurrence is 2,000 km2
Altitude range: 2500-4050 metres above sea level.
Habitat and ecology: It grows in grasslands at high altitudes, on slopes of the western edge of the Andean desert. Mainly on sandy and rocky soils in close association with the local form of Maihueniopsis glomerataSN|7369]]SN|7342]] (camachoi) and Cumulopuntia bolivianaSN|4047]]SN|4047]] subsp. ignescens (hystrix). There are no threats, it is abundant, it occurs in a protected area, and easily reproduces vegetatively. The species is collected as an ornamental for specialized collections outside Chile. It reproduces by seed and spreads vegetatively by means detached joints or cladodes, which can take root and establish themselves as independent individuals.

Description: Maihueniopsis conoideaSN|7342]]SN|7369]], sometime considered a local or morphological form of the widespread and variable Maihueniopsis glomerataSN|7369]]SN|7342]], differes from the latter mainly for its usually smaller segment size in small flat clusters. Throughout its natural range there is considerable variation in segment size, spine colour and spine count per areola.
Habit: This cactus forms dense and small cushions.
Stems (joints): Tapered-conical to spheroidal to 2 to 4 cm long, something sharply pointed and not tuberculate.
Areoles: About 20 small.
Spines: Concentrated in upper areoles of the joint, the apex of which sometimes without spines.
Central spines: 1-2 very variable, stout to bristly, long to short, up to 5 cm long flat, straight or slightly curved. Sometimes absent (spineless).
Radial spines: 0 to 2, bristly.
Flowers: Up to 5 cm, pale yellow. Pericarpel obconic.
Fruit: Globular, large green or yellowish spineless.
Seeds: Lenticular creamy-brown 2.5 to 4 mm with

Cultivation and Propagation: Maihueniopsis conoideaSN|7369]]SN|7369]] cannot endure any standing heat and need an absolutely airy and sunny place this brings very healthy plants with a good spination and flowers, but often in cultivation the plants are rarely so compact as they are best grown inside a greenhouse because of our very humid weather in North Europe and America which gives a relatively low light intensity compared to the temperature. However, this species takes considerable frost and is certainly worth growing.
Soil: Use a very draining compost-mix with a high mineral content, they needed deeper pots to accommodate the big tap root.
Watering: Water and feed in the vegetation period from April until to mid of September, keep dry and cool in winter, they have to be stimulated to bloom by dryness and you may give them water first when the plants start to produce the new buds.
Repotting: Generally, these plants should be re-potted every other year, in order to provide fresh soil. Pot bound, starved plants will rapidly look tatty and won’t flower well.
Hardiness: Hardiness Zone 8. The plant tolerates low temperatures (-8°C), can tolerate occasional snow cover for up to a couple of weeks per year.
Propagation: Cuttings (let dehydrate the cuttings for a few weeks and the roots will coming quick). To get new clones it is necessary to use seeds. Seeds require some preliminary manipulations, in fact, the shell/husks of the seeds are very hard (like a hazelnut), it is necessary to soak the seeds 24 hours, and break or scarify the husks before planting, by any means. In these conditions, germination occurs in 5 or 6 days. Otherwise, with intact seeds, germination can take several months or even years.
