Discocactus

Discocactus  

Discocactus is a genus of cacti known for its spherical shape and nocturnal flowering. It is a rare and highly prized plant among collectors due to its beauty and uniqueness.  

Description  

Shape: Small, globular, or hemispherical, typically dark green in color.  

Size: Varies by species, usually between 4 and 12 cm in diameter.  

Areoles: Covered with small, stiff spines, typically white or yellowish.  

Flowering: Produces large, fragrant, white or cream-colored flowers that bloom at night and are pollinated by moths.  

Origin and history  

Origin: The Discocactus genus is native to South America, specifically Brazil, Paraguay, and Bolivia.  

Habitat: Grows in rocky and sandy soils in warm, dry climates. It is often found on slopes or nestled in rock crevices.  

History: The name Discocactus derives from the Greek word "diskos" (disk), referring to its flat growth pattern during its early stages. It has been documented since the 19th century as a rare and endangered genus in its natural habitat.  

Curiosities  

1. Many Discocactus species are endangered due to habitat loss.  

2. Its nocturnal flowers are not only stunning but also specifically adapted to attract certain pollinators like moths.  

3. In mature plants, a "cephalium," a woolly structure at the top of the cactus, develops and serves as the base for flower production.  

4. Once it blooms, the flowers typically last only one night.  

Care  

- Light  

Requires bright indirect light or full sun but should be protected from intense midday sunlight to avoid burns.  

- Soil  

Needs well-draining soil, such as a cactus mix with coarse sand or perlite. Avoid compact soils that retain moisture.  

- Temperature  

Thrives in warm climates, between 20-30°C, and does not tolerate temperatures below 10°C.  

- Watering  

Moderate watering, allowing the soil to dry out completely between waterings.  

In winter, drastically reduce watering as the plant enters dormancy.  

Avoid letting water accumulate at the base of the cactus.  

- Fertilizing  

During the growing season (spring and summer), apply liquid cactus fertilizer every 4-6 weeks.  

Pruning  

Does not require regular pruning.  

Only remove dry or damaged parts using clean tools to prevent infections.  

Propagation  

Usually propagated by seeds, as it does not produce offsets like other cacti. This is a slow process that can take months.  

With proper care and patience, Discocactus can become a true gem in any cactus collection.
