Aloe Castilloniae

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.

Tulista pumila (formerly Haworthia pumila) is a striking and slow-growing succulent native to the Western Cape of South Africa. Known for its architectural beauty, this plant forms compact rosettes of thick, fleshy, dark green to brownish leaves covered with prominent raised white tubercles, giving it a textured, bumpy appearance.

Tulista pumila can grow up to 20 cm (8 inches) tall and wide, with mature plants producing tall, slender flower stalks bearing small, tubular, pale pink to white flowers—typically blooming in late spring to summer. The leaves are triangular and curved inward, often with toothed margins, adding to its ornamental value.

This species is drought-tolerant and prefers well-draining soil, partial sun to bright indirect light, and minimal watering—making it ideal for rock gardens, succulent collections, or container displays. Tulista pumila is also prized for its resilience and unique form, often regarded as one of the most attractive members of the Tulista genus.

Euphorbia neurobella (Red Monadenium)

A striking and unusual succulent, Euphorbia neurobella is admired for its thick, sculptural stems and rich reddish tones that intensify in bright light. Its knobbly, textured surface gives it a bold, almost otherworldly appearance, making it a standout piece in any collection. During its growing season, it produces small, delicate flowers that add subtle charm to its rugged form.

Perfect for collectors looking for something different, this plant thrives in warm, bright conditions with well-draining soil and light watering.

Interesting fact:
Euphorbia neurobella was once classified under the genus Monadenium, which is why it’s still commonly known as “Red Monadenium” among collectors.
