It is a summer grower species and does not require any special treatment. Water regularly from Spring to Autumn, but do not overwater. Requires full sun or light shade and careful watering to keep plant compact with strong spines. It will stand as much sun as you can give it, as long as there is good air circulation.
Needs good drainage and very porous potting mix, it can become too elongated if compost is too rich.
It will flower much better if it has a cool resting period during the winter, when little or not water is given. Frost Tolerance: Hardy to -7° C.
Description: Solitary cactus that can in time grow several heads.
Stem: Light green, up to 10 cm tall and 10 cm wide.
Flowers: Funnel-shaped, pink (or magenta) with a yellow center and about 6 cm wide Not self-fertile.
Blooming season: Usually flowers only once in mid to late winter (or early spring) but sometimes it can do a 2nd round like it happens with all seasonal bloomers once in a while.
