Stenocactus multicostatus

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.

Adromischus marianiae – Clanwilliam Form

A fascinating South African succulent prized by collectors for its unusual, highly textured leaves. This locality form from the Clanwilliam area of the Western Cape develops thick, compact leaves that may range from green and grey-green to reddish or deep burgundy, particularly when grown in strong light.

🌱 Care: Grow in bright light with some protection from intense midday summer sun. Use a very well-draining, mineral-rich succulent mix. Water thoroughly during active growth, but allow the soil to dry completely before watering again. Keep considerably drier during dormancy.

✨ Interesting fact: Adromischus marianiae is extremely variable, and locality forms are especially valued by collectors because plants from different populations can differ dramatically in leaf shape, texture and colour.

⭐ A must-have South African species for collectors of rare and unusual succulents.
