Gymnocalycium mihanovichii variegata

Tylecodon buchholzianus is a winter-growing succulent shrub native to the arid regions of South Africa, particularly the Western and Northern Cape. Like other members of the genus Tylecodon, it is well adapted to long, dry summers and produces leaves only during the cooler growing season.

Characteristics:

• Forms a branching shrub with a thickened, often sculptural base.
• Stems may become woody and grey with age.
• Leaves are fleshy, green, and appear mainly in winter (active growth period).
• Produces tall flower stalks bearing small tubular flowers, usually greenish to yellowish or pinkish depending on form.
• The plant typically enters full dormancy in summer, shedding its leaves.

Cultivation:

• Winter-growing succulent.
• Requires very well-drained soil and a dry summer dormancy.
• Water moderately during autumn–spring growth.
• Keep almost completely dry in summer.
• Prefers full sun to bright light conditions.

Notes:

• Like many Tylecodon species, it contains toxic compounds and should not be consumed by animals or humans

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.
