Echevaria setosa dementia crested in pot

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.

Ornithogalum is a genus of bulbous flowering plants in the asparagus family (Asparagaceae), native mainly to southern Africa and parts of Europe and western Asia. The group includes many species commonly called “star-of-Bethlehem” due to their star-shaped flowers.

General characteristics:

• Grows from underground bulbs (geophytes).
• Produces narrow, strap-like green leaves.
• Flowers are typically star-shaped with 6 white (sometimes green-striped) petals.
• Many species open in sunlight and close in low light or at night.
• Flowering season varies by species, but many South African types bloom in spring.

Habitat:

• Found in grasslands, renosterveld, fynbos edges, and rocky or sandy soils.
• Many species are adapted to seasonal rainfall patterns (winter or summer rainfall depending on region).

Cultivation:

• Prefers well-drained soil and full sun.
• Requires a dry dormancy period after flowering when leaves die back.
• Water lightly during active growth; avoid overwatering during dormancy.
• Bulbs can multiply over time, forming clumps.

Notes:

• Some species are highly ornamental, while others are considered invasive outside their native range.
• A few species may be toxic to livestock if ingested.
