Notocactus Scopa Inermis Cristata
The Notocactus Scopa Inermis Cristata is a rare and spectacular cactus form resulting from a mutation of the Notocactus Scopa Inermis. This so-called "crested" mutation gives the plant a fan-shaped or wavy crest growth instead of the classic spherical form. The result is a highly graphic, unique plant, very sought after by collectors for its striking appearance.
Unlike the standard form, this crested variant is partially or completely spineless, highlighting the curved lines of the crest and the geometry of the ribs. Each specimen is different: some form dense waves, others narrower and more twisted crests. The cactus body is usually light green to blue-green, covered with small woolly areoles aligned along the undulations.
This form is generally grafted to ensure longevity, although it can also be grown on its own roots with proper drainage. Flowering is possible, though occasional, and appears as small yellow flowers on the top of the crest.
🌤️ Bright but filtered light: Recommended year-round. Avoid direct sun during summer.
🌞 Ideal placement: Temperate greenhouse, veranda, or windowsill with light shading.
⚠️ Warning: Insufficient light causes crest collapse, color loss, and unbalanced growth.
🌱 Spring / summer: Water when the substrate is completely dry (every 2 to 3 weeks). Water at the base only, never directly on the crest.
🍂 Autumn / winter: Almost completely stop watering to avoid rot.
💡 Tip: Grafted plants consume more water, but always with moderation.
🌡️ Ideal range: Between 18 and 26 °C.
❄️ Minimum: 5 °C if the substrate is perfectly dry.
🏠 Winter care: Keep in a bright, airy, unheated location protected from frost.
🪨 Recommended substrate: 50% cactus substrate + 50% draining materials (perlite, gravel, pumice).
🧱 Tip: For grafted forms, a slightly richer substrate at the base can be tolerated.
🌸 Season: Spring or early summer.
🎨 Color: Pale yellow, funnel-shaped.
💡 Tip: A dry winter rest followed by a light nutrient supply in spring encourages flowering.
