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.

Mammillaria Camptotricha cv. Curlispina is a rare and highly sought-after cactus admired for its unusual curled white spines that resemble tangled ribbons or soft wool. This compact species forms small clusters and creates a striking display in any succulent or cactus collection. During flowering season, it produces delicate creamy-white to pale yellow flowers that beautifully contrast with its twisted spines. It thrives in bright light, well-draining soil, and careful watering.

Interesting Fact:
The name “Curlispina” literally refers to its curly spines, which help reflect intense sunlight in its natural environment and protect the plant from excessive heat.

Original Habitat:
Originally native to the dry limestone regions of central Mexico, especially in areas with arid conditions and rocky terrain.
