Stenocereus eruca

Stenocereus eruca, also known as the Creeping Devil, is a fascinating cactus species native to the deserts of Baja California in Mexico. It's known for its unique growth habit and striking appearance. Here's a detailed description along with some cultivation tips:

Description

1. Growth Habit: The most distinctive feature of Stenocereus eruca is its growth pattern. It grows horizontally along the ground, rather than vertically, and can reach lengths of up to 2 meters (6 feet). Over time, the trailing end of the cactus dies off while the leading edge continues to grow forward.
2. Stem: The stems are thick and cylindrical, with a blue-green color. They can be up to 15 cm (6 inches) in diameter.
3. Ribs & Spines: It typically has 12-17 ribs. The spines are long, strong, and can be up to 4 cm long, ranging in color from yellow to gray.
4. Flowers & Fruits: It produces nocturnal flowers that are white or slightly pink, which later develop into red fruits. The fruits are edible and have a sweet taste.

Cultivation Tips

1. Lighting: Needs full sun exposure for optimal growth. In a home setting, place it in the brightest spot available, like a south-facing window.
2. Watering: Like most cacti, Stenocereus eruca is drought tolerant. Water sparingly and allow the soil to completely dry out between waterings. Overwatering can lead to root rot.
3. Soil: Requires well-draining soil. A cactus mix or a blend of regular potting soil with sand or perlite works well.
4. Temperature: It thrives in hot, arid environments. Ensure it's kept in a warm location during the growing season and protect it from frost in winter.
5. Fertilizing: Use a diluted cactus fertilizer during the growing season (spring and summer). Do not fertilize in winter.
6. Repotting: Repot every few years to refresh the soil. Be cautious of the spines when handling.
7. Propagation: Propagation is typically done through stem cuttings. Allow the cutting to callous over for a few days before planting in well-draining soil.

When cultivated under the right conditions, Stenocereus eruca is a unique and conversation-starting addition to any cactus collection. Its unusual growth habit and resilience make it a fascinating plant for cactus enthusiasts.
