Most cactus are from the deserts of the world and as such like to go totally bone dry between waterings, making them very low-maintenance. If you see your cactus begin to shrivel or lose firmness, your cactus is likely totally dry and should be watered. To get good healthy growth your plant does not want to sit around totally dried out during its growing season. Once it is dry, water it. This cactus comes from an area with summer rainfall and is actively growing during that time, when it is forgiving of overwatering errors. During winter dormancy it should be kept extra dry and won't tolerate overwatering. If possible, protect from winter rains. Remember that if kept in a small pot your plant will want more frequent watering. | |

Growing Notes
While spine production is better, creating a woolier plant, in sunny spots, push this plant into hot inland sun and it will burn.
Makes a great houseplant near, but not right in, a sunny window.
This plant is typically grown in a pot or a very gritty rockery. It shouldn't be planted in typical garden soil.
Unlike the typical species of this plant, which has burnt orange flowers, this one has very unusual green blooms.
