Cacti - Pincushion Cactus Johnstonii

Mammillaria johnstonii – Red-Blooming Pincushion Cactus | Rare, Compact, and Effortlessly Striking

Bring a pop of vivid colour and sculptural charm to your plant collection with Mammillaria johnstonii, a rare and eye-catching cactus native to Mexico’s desert landscapes. This compact species forms neat clusters of spherical, blue-green stems wrapped in a delicate web of fine white spines, giving it a soft, textural appeal.

In spring, it transforms into a living jewel—crowned by a perfect halo of brilliant red blooms that encircle the top, creating a dramatic contrast against its spiny form. After flowering, small, red, club-shaped fruits add an extra splash of ornamental interest.

Standout Features:

• Architectural Beauty: Symmetrical, spherical stems covered in elegant white spines.
• Vivid Floral Display: Striking red blooms form a perfect ring each spring.
• Low-Maintenance: Thrives on minimal watering—perfect for beginners.
• Compact Form: Fits beautifully on windowsills, desks, patios, or in terrariums.
• Year-Round Interest: Attractive even without flowers, with bonus fruits after blooming.

Care Guide:

• Light: Bright, indirect light; protect from intense afternoon sun.
• Water: Let soil dry completely between waterings; water less in winter.
• Soil: Use a fast-draining cactus/succulent mix
