The plant is totally without thorn and of gray color. It is easily hiding in its environment. The plant apex contains a woolly structure from which emerge big pink or yellow flowers, but only after several years. The plant contains bitter and toxic alkaloids such as hordenine. These protect the plant against consumption by herbivores. Care of Ariocarpus Ariocarpus species have a tuberous root system and are quite sensitive to soil conditions, preferring sharply draining loam based soils with minimal humus. Care should be taken to avoid over-watering, allowing the soil to dry out completely between watering. Plants require water only during periods of summer growth and should be kept perfectly dry overwinter, with a minimum temperature of 12 C, although certain species can cope with considerably cooler conditions.
