Cleistocactus winteri f. cristata - Golden rat tail cactus

Cleistocactus winteri f. cristata, also known as the Golden Rat Tail, is a fascinating form of Cleistocactus winteri, prized for its wavy and sinuate habit that gives it an extraordinary appearance. Its stems, covered with small golden thorns, form irregular crests that intertwine. Native to the arid regions of Bolivia and Argentina, this cactus is hardy and easy to care for. Place it in a beautiful pot on a well-exposed windowsill!

Cleistocactus winteri f. cristata belongs to the Cactaceae family and originates from a natural mutation of Cleistocactus winteri, a creeping cactus native to Bolivia. This cristate form is distinguished by its flattened and sinuate stems, which grow in a disorderly manner instead of spreading into long trailing shoots. Indoors, it typically reaches 30 to 50 cm in diameter, forming a compact and wavy mass. Its epidermis, covered with small, fine golden thorns, gives it a fuzzy appearance. At maturity, it may produce tubular orange-pink flowers, although flowering is rare in indoor cultivation.

Cleistocactus winteri f. cristata requires a very bright exposure, with several hours of direct sunlight per day. It tolerates heat well and can be placed outdoors during the warmer months. This plant must be protected from the cold, as it cannot withstand temperatures below 5 °C. Its substrate must be very well-draining, composed of a mix of cactus compost, coarse sand, and perlite, to avoid excess moisture. Water moderately, allowing the soil to dry completely between waterings. In winter, it is best to reduce watering significantly to avoid the risk of rot. While not highly susceptible to diseases, it can still be affected by mealybugs.

Cleistocactus winteri f. cristata has small, fine thorns that can be irritating if they come into contact with the skin. It is recommended to handle it with care and to keep it out of reach of children and pets.

With its compact habit and undulations, Cleistocactus winteri f. cristata makes a striking statement in a bright living room, conservatory, or greenhouse. It is often grown alone to showcase its unique form but can be paired with other sculptural cacti of different shapes, such as Astrophytum myriostigma or Mammillaria elongata. A wide and shallow terracotta pot will improve drainage and highlight its original texture.
