Stenocactus multicostatus

Coryphantha elephantidens cv. Tanshi Zougemaru inermis is a rare, spineless cultivar of Coryphantha elephantidens, originally native to central Mexico, especially in Jalisco and surrounding regions. This particular cultivar is known for its smooth, rounded, and highly symmetrical tubercles (bumps) that give it a sculpted, almost “puffy” appearance.

Unlike the typical species, the inermis form lacks spines, making it especially attractive to collectors. It may produce large, showy pink to magenta flowers in summer. It prefers full sun to light shade, well-draining soil, and minimal watering.

Pseudolithos caput-vaporae

A rare and fascinating succulent prized by collectors for its unusual, sculptural appearance. Pseudolithos caput-vaporae develops a compact, irregularly shaped body with a distinctive textured surface, resembling a small piece of living stone.

Its unique form and muted green to grey-green colouring make it an excellent choice for specialist succulent collections. A true collector’s plant, it is best grown in a very well-draining, mineral-rich medium with plenty of bright light.

Water sparingly and only when the growing medium is completely dry. Avoid prolonged moisture around the roots, as Pseudolithos can be particularly sensitive to overwatering.

Gymnocalycium mihanovichii is a small, globular cactus species native to the semi-arid regions of Paraguay and parts of northern Argentina. It belongs to the Cactaceae family and is part of a genus known for its relatively easy care, compact size, and attractive flowers.

This species typically grows to about 5–6 cm in height and 4–5 cm in diameter. It has a flattened, spherical body with 8–14 broad ribs and a grayish-green to dark green color. The stem is often slightly wrinkled and marked by low tubercles. It bears short, slightly curved spines that vary in number but are generally not aggressive, making the plant user-friendly for handling.

Flowers appear from the crown of the plant during late spring to summer. They are funnel-shaped and range in color from pale pink to light purple, occasionally white. The blooms are relatively large compared to the size of the plant and open during the day.

This species prefers well-draining cactus soil, moderate watering (allowing the soil to dry completely between waterings), and bright, indirect sunlight. Direct sun in hot climates can cause sunburn on the plant’s surface. It tolerates mild cold but should be protected from frost.

In cultivation, Gymnocalycium mihanovichii is often the parent of colorful grafted hybrids like the “Moon Cactus” (var. friedrichii), which lacks chlorophyll and must be grafted onto a host plant to survive.
