Myrtillocactus Geometrizans Crest (Dinosaur Back)

Myrtillocactus geometrizans 'Crested'
Common Name: Dinosaur Back Cactus

Myrtillocactus geometrizans 'Crested', also known as the Dinosaur Back Cactus, is a wildly sculptural, fan-forming mutation of the classic blue Myrtillocactus. Instead of growing upright columns, this crested form develops thick, undulating ridges and folds—often resembling the spiny back of a dinosaur or a desert mountain range frozen in time.

The powdery blue-green skin and chunky ribbed texture make each plant look like a living sculpture. Every crest is unique—some are flat and wide, others twist and curl in unpredictable directions. It’s slow-growing, incredibly hardy, and a true conversation piece for any collector or design-forward plant display.

☀ Light Requirements
Thrives in full sun to bright, indirect light. Outdoors, it loves full sun with good airflow. Indoors, place near a bright window and rotate occasionally to encourage even growth.

💧 Watering Needs
Water deeply when soil is fully dry. Like all Myrtillocactus, it’s drought-tolerant and sensitive to overwatering—especially in cooler seasons. Reduce watering in winter.

🌡 Temperature Tolerance
Cold-hardy to about 25–30°F in dry conditions. Protect from frost and freezing wet soil. For winter shipping, consider adding a [Heat Pack].

✨ Special Features
• Crested Growth – Dramatic fan-like folds resemble a dinosaur’s back
• Powdery Blue Color – Subtle glaucous tones give it a frosty, otherworldly look
• Collector Favorite – Each crest is one-of-a-kind and highly sought-after
