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.

Haworthia retusa Variegated

A beautiful and highly desirable form of the South African Haworthia retusa. It forms compact rosettes of thick, triangular leaves with characteristic translucent “windows”. The variegated form develops striking cream, yellow or white markings mixed with green, making every plant unique.

🌱 Care: Bright filtered light or approximately 50–60% shade; avoid harsh midday sun, especially on the pale variegated sections. Use a very well-draining mineral-rich succulent mix and allow it to dry between waterings.

✨ Interesting fact: The transparent leaf windows allow light to penetrate into the leaf—an adaptation associated with Haworthias that grow partly recessed into the soil.

⭐ A must-have for Haworthia collectors, particularly specimens showing strong, balanced variegation.
