Echinopsis Oxygona
The Echinopsis Oxygona is a globular cactus highly appreciated for its robustness, ease of cultivation, and above all for its impressive funnel-shaped flowers. Its blooms are spectacular: large pink to purple corollas reaching up to 20 cm in diameter open, often in large numbers, at the end of long floral tubes.
The body of the cactus is globular to slightly cylindrical with age, dark green in color, featuring 8 to 14 rounded ribs lined with woolly areoles from which emerge fine beige or light brown spines.
Very popular with both beginners and collectors, Echinopsis Oxygona combines prolific flowering, hardiness, and simple cultivation. It often produces offsets at its base, eventually forming beautiful flowering clumps.
The Echinopsis Oxygona is native to the arid regions of Brazil, Uruguay, Argentina, and Paraguay. It grows on rocky plains and sunny slopes, often partially sheltered by shrubs.
In its natural habitat, it benefits from well-drained soils, strong sunlight, and a marked alternation between the rainy season and the dry season.

For abundant flowering, Echinopsis Oxygona requires strong light:
🌞 Full sun: at least 6 hours per day, especially in spring and summer.
🌤️ Light shade during heatwaves to avoid sunburn on young plants.
💡 Insufficient light greatly reduces flowering potential.

Echinopsis Oxygona enjoys regular but moderate watering during its growth phase:
🌱 Spring / summer: water every 10 to 15 days depending on temperature and drainage. Always wait until the substrate is completely dry.
🍂 Autumn / winter: stop watering as soon as temperatures drop below 10°C.
⚡ Golden rule: excess moisture must be avoided. The pot must always have a drainage hole.

Echinopsis Oxygona is a fairly tolerant cactus:
🌞 Ideal temperature: between 20°C and 30°C.
❄️ Hardiness: can tolerate down to -4°C occasionally if kept dry, but should ideally be protected from 5°C.
🏠 Winter rest: bright, dry, and cool conditions to stimulate flowering the following spring.
