The Cereus peruvianus INERMIS SPIRALIS is a particularly striking and rare cultivar of the Cereus peruvianus, also known as the Peruvian Apple Cactus. This variety is known for its unique spiraling growth pattern and variegated coloring, making it a highly sought-after plant among cactus enthusiasts. Here's a detailed description and some cultivation tips:
Description
-
Growth Form: Unlike the standard columnar growth of typical Cereus peruvianus, the 'Spiralis' exhibits a distinctive spiral growth pattern, with the ribs of the cactus twisting around its axis.
-
Variegation: This variety features variegated coloring, meaning it has patches or streaks of different colors. This typically includes shades of green, creamy white, or yellow, adding to its ornamental value.
-
Size: It grows more slowly and may be smaller than the non-spiral, non-variegated varieties. Over time, it can reach impressive heights, often several feet tall.
-
Spines: Spines are usually present but may be less prominent than in the standard form, allowing the spiral pattern and variegation to be more visible.
-
Flowers: Capable of producing large, fragrant, white flowers, though flowering is less common in cultivated and variegated forms. These flowers typically open at night.
Cultivation Tips
-
Lighting: Requires full sun to partial shade. Adequate sunlight is essential for maintaining the spiral growth pattern and vivid variegation.
-
Soil: Prefers well-draining cactus mix. Ensure good drainage to avoid root rot.
-
Watering: Water moderately in the growing season and reduce watering in the winter. Allow the soil to dry out between watering sessions.
-
Temperature: It is somewhat cold-tolerant but should be protected from frost. Ideal growing temperatures are warm and consistent.
-
Fertilizing: Use a balanced cactus fertilizer during the growing season to support healthy growth.
-
Propagation: Propagation is typically done through cuttings, but maintaining the variegation in offspring can be challenging.
-
Placement: Ideal as an indoor plant in a sunny location or in a cactus garden where its unique form can be displayed.
-
Handling: Handle with care during repotting or moving, as the spines, though fewer, can still be sharp.
Unique Aspects
- The combination of the spiral growth form and variegation makes each specimen unique.
- Its striking appearance makes it a collector's item and a focal point in any garden or collection.
The Cereus peruvianus INERMIS SPIRALIS is not just a cactus but a living sculpture, offering a mesmerizing blend of geometry and color. While it requires similar care to other cacti, its unique appearance makes it a rewarding plant for collectors and enthusiasts.
