Ferocactus glaucescens f. inermis, also known as the Spineless Blue Barrel Cactus or Nude Blue Barrel Cactus, is a fascinating variety of the Ferocactus glaucescens cactus. It's a popular choice for xeriscaping and desert gardens due to its drought tolerance and striking appearance.
Key Characteristics:
- Spineless: Unlike its spiny relatives, this form has been cultivated to be spineless, making it safer for gardens with pets and children. However, some small bristles or bumps might still be present.
- Blue-green Stem: It has a distinct blue-green color due to a waxy coating that protects it from the sun.
- Globose to Barrel Shape: It starts as a bumpy, globular shape and matures into a large barrel cactus with prominent ribs.
- Slow Growth: It's a slow-growing cactus, but with proper care, it can live for decades.
- Flowers: It produces beautiful lemon-yellow, funnel-shaped flowers in late spring and summer.
- Fruits: The flowers are followed by white, fleshy fruits.
Habitat and Origin:
- Native to Eastern Central Mexico, specifically the rocky limestone slopes in deciduous dry forests and juniper scrub woodlands of Hidalgo, Guanajuato, Querétaro, and San Luis Potosí.
Care and Cultivation:
- Sunlight: Requires full sun or partial shade. Prefers late afternoon sun.
- Temperature: Thrives in warm, dry conditions, preferably above 75°F. Avoid consistent temperatures below 40°F. If you live in a region with freezing temperatures, bring it indoors during winter.
- Soil: Needs well-draining soil, such as a cactus and succulent mix with high mineral grit (like coarse sand, pumice, or perlite).
- Watering: Drought-tolerant and needs infrequent watering. Water deeply and allow the soil to dry out completely between waterings. During winter dormancy, keep it extra dry.
- Humidity: Prefers low humidity.
- Hardiness Zone: Hardy in USDA zones 9-11.
Additional Notes:
- The name "Ferocactus" means "fierce or savage" due to the sharp spines of many species in the genus.
- This cactus can live for over 100 years in the wild and up to 50 years in cultivation.
- It is reportedly used in traditional medicine by indigenous peoples in Mexico to treat digestive issues and skin conditions.
