Ariocarpus kotschoubeyanus is small cactus with a usually solitary, flat-topped stem that grows up to 3 inches (7.5 cm) in diameter (usually much smaller), reaching flowering size at slightly more than 0.5 inches (1.3 cm) in diameter. Tubercles are small, triangular, and bear felted groves along their midlines. Flowers are up to 1 inch (2.5 cm) in diameter and may range from nearly white or shell pink to bright magenta.
USDA hardiness zones 9a to 11b: from 20 °F (−6.7 °C) to 50 °F (+10 °C).
How to Grow and Care
You should plant your Ariocarpus in soil specifically formulated for cacti. You can buy a cactus mix at your local nursery. Do not use generic soil mixes because they will not provide enough aeration and drainage. Additionally, using a container without a hole, whether it is a pot or a terrarium, is a bad idea for the same reason.
Ariocarpus need a lot of sunlight. However, in hot, dry areas, they can be damaged by excessive sunlight, so you should either use a shade-cloth to limit their sun or move them out of the sun during the hottest hours of the day. In more temperate areas, direct sunlight is fine.
These cacti prefer to be kept at room temperature or slightly lower and in low humidity.
Water your Ariocarpus when it is dry, but then wait until the soil dries out completely to water it again. The amount of time this takes will vary depending on your climate and the size of your pot if you use one. See more at: How to Grow and Care for Ariocarpus.
