Haworthia Retusa Variegated in Pot

Sulcorebutia augustinii

A beautiful and highly collectible miniature cactus admired for its compact growth and delicate, intricate appearance. Sulcorebutia augustinii forms small, rounded to slightly elongated bodies covered with closely spaced ribs and fine spination. Under the right conditions, it produces attractive, brightly coloured flowers that create a striking contrast with the plant’s body.

A wonderful choice for collectors of miniature and rare cacti. Provide bright light, excellent air circulation and a very well-draining, mineral-rich growing medium. Water thoroughly during active growth, allowing the soil to dry completely between waterings, and keep the plant mostly dry during winter dormancy.

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.
