Myrtillocactus geometrizans 'Cristata' - Crested Blue Candle Cactus

Crested Blue Candle Cactus - Myrtillocactus geometrizans 'Cristata'

Myrtillocactus geometrizans 'Cristata' is a rare and mesmerizing crested form of the Blue Candle Cactus, known for its sculptural, undulating blue-green growth. Native to Mexico, this variety develops an unusual fan-like structure due to a natural mutation affecting its apical meristem. Unlike its standard counterpart, which grows in upright, branching columns, this form exhibits unpredictable and intricate crested patterns, making it highly sought after by collectors.

Distinctive Features

• Crested Growth: Unlike the upright, branching habit of the standard Blue Candle Cactus, this variety forms intricate, wave-like ridges.
• Waxy Blue-Green Stems: Retains the signature glaucous-blue coloration, helping reduce water loss in arid conditions.
• Rapid Growth: Grows faster than many cacti, developing dense crested formations over time.

Care Tips

• Light: Prefers full sun to partial shade; bright light enhances its color and cresting pattern.
• Water: Water sparingly, allowing the soil to dry completely between waterings.
• Humidity: Thrives in low humidity; avoid excessive moisture to prevent rot.
• Temperature: Best suited for warm climates (18–30°C) but should be protected from frost.
• Fertiliser: Apply a diluted cactus fertiliser during the active growing season (spring and summer).
• Potting: Requires well-draining soil; a mix of sand, perlite, and potting soil is recommended.
• Propagation: Typically propagated by cuttings, though cresting may not always be retained.

Additional Notes

• Often grafted onto a standard *Myrtillocactus geometrizans* base to enhance stability and vigour.
• Rarely flowers, but when it does, it produces small, greenish-white blooms followed by dark berries.
• Non-toxic to pets, making it a safe and intriguing houseplant.

Myrtillocactus geometrizans 'Cristata' is a striking and unusual variation of the Blue Candle Cactus, offering a dramatic, sculptural appearance. Its relatively fast growth and easy care make it an excellent choice for collectors seeking a distinctive and conversation-worthy addition to their succulent collection.
