Botanical Name:
Mammillaria spinosissima
Common Names:
Red-Headed Irishman
Plant Category:
Cactus
Plant/Product Description:
Mammillaria spinosissima, commonly known as the Red-Headed Irishman, is a striking, globular cactus that features dense clusters of fine, white spines that form a soft, pincushion-like appearance. What sets this cactus apart is the striking red or orange coloration on the top of the plant, which resembles a "red head" and gives it its common name. Mammillaria spinosissima blooms with small, pink or purple flowers that add a beautiful contrast to its fiery spines. This compact cactus is ideal for containers, cactus collections, or as part of a desert-themed garden.
Plant Care Notes:
- Sunlight: Prefers full sun for optimal growth and flowering. Can tolerate some partial shade, but full sun produces the best results.
- Watering: Water thoroughly when the soil is dry to the touch. Allow the soil to dry completely between waterings to prevent root rot.
- Soil: Requires a well-draining cactus mix or succulent mix with added perlite or pumice for optimal drainage.
- Temperature: Thrives in temperatures between 70°F and 85°F (21°C to 29°C). Not frost-tolerant and should be protected from freezing temperatures.
- Dormancy: Mammillaria spinosissima is dormant in the winter, requiring minimal water during this period.
- Propagation: Can be propagated by offsets or seeds.
- Pests: Generally pest-resistant but may occasionally attract mealybugs or aphids.
Toxicity:
Mammillaria spinosissima is non-toxic to humans and pets, making it a safe addition to homes and gardens.
