Notocactus Scopa

The Notocactus Scopa is a South American globular cactus highly appreciated by enthusiasts for its silhouette covered with golden spines and its vivid flowering. Compact, hardy and spectacular in pots or planters, it fits perfectly into a collection or on a well-sunlit windowsill.

Its shape is generally spherical to slightly cylindrical, reaching up to 15 cm in height at maturity. It has between 20 and 30 well-defined ribs, regularly spaced, bearing woolly areoles from which emerge numerous golden radial spines, fine but sharp, sometimes intertwined. The apex is often covered with a fine white down that is very decorative.

The Notocactus Scopa produces magnificent funnel-shaped flowers, generally yellow, sometimes tinged with orange at the center. They appear in a crown at the top of the plant in spring and summer, offering a striking contrast with the green epidermis and the golden reflections of the spines.

The Notocactus Scopa originates from southern Brazil, Paraguay and Uruguay. It grows in semi-arid mountainous regions, often on rocky outcrops well exposed to the sun, in shallow mineral soils.
Light exposure is a key factor for the health of the Notocactus Scopa. Abundant light maintains its compact shape and promotes flowering.

🌞 Direct sunlight: Ideally 4 to 6 hours per day. It enjoys a very bright location, even indoors.

🌤️ In summer: If the sun is too strong, provide light filtered shade during the hottest hours.

⚠️ Warning: A lack of light leads to etiolation and duller epidermis coloration.
Proper water management is essential to avoid rot and stimulate growth.

🌱 Spring / summer: Moderate watering every 2 to 3 weeks, only when the substrate is dry deep down.

🍂 Autumn / winter: Gradually reduce until watering is completely stopped if the plant is resting in cool conditions.

💡 Tip: Always water around the edge of the pot, never at the center, to prevent moisture accumulation at the collar.
The Notocactus Scopa tolerates relatively wide temperature variations but does not tolerate frost.

🌡️ Comfort range: 18°C to 28°C.

❄️ Lower limit: Down to 5°C if the plant is perfectly dry.

🏠 Wintering: Place the plant in a bright, cool and airy room between November and March.
A good substrate guarantees the plant’s longevity and health.

🪨 Ideal mix: 50% cactus substrate + 50% draining materials (pumice, perlite, coarse sand).

🧪 Tip: Add a layer of gravel at the bottom of the pot to prevent excess stagnant water.
The Notocactus Scopa can offer bright flowering every year if conditions are respected.

🌸 Period: Spring to summer.

🎨 Color: Bright yellow, sometimes orange-tinged, open corolla.

⏳ Duration: 3 to 5 days, with possible succession over several weeks.
