Description
Myrtillocactus geometrizans f. cristata is a spectacular crested form of the Blue Myrtle Cactus, prized for its striking fan-shaped growth and beautiful blue-green colour. Instead of growing upright like the standard species, this rare mutation develops intricate folds and undulating ridges, creating a living sculpture that becomes more impressive with age.
Its unique appearance makes it a standout addition to any cactus collection, while its hardy nature and easy care requirements make it suitable for both beginners and experienced collectors. Every plant develops its own distinctive crest, ensuring that no two specimens are ever alike.

Pet Safety: 🐾 Use Caution Around Pets
Myrtillocactus geometrizans is not considered toxic to cats or dogs. However, its spines can cause injury if touched or chewed, so it is best displayed out of reach of curious pets and young children.
Good to Know
The crested form develops through a natural growth mutation known as fasciation, where the growing point expands into a fan-shaped crest instead of a single stem. This rare mutation produces the intricate folds and rippling forms that collectors value so highly. Because each crest develops differently, every plant is completely unique.
Please Note: As a living plant, each specimen is unique. Crest shape, branching, colour and spine development will vary from plant to plant, making every example an individual collector’s piece.
