Astrophytum myriostigma cv. Kikko

The Bishop's Cap Cactus 'Kikko' (Astrophytum myriostigma cv. Kikko) is a cultivated variety within the Cactaceae family, native to the highlands of central Mexico. This striking cactus displays a unique geometric pattern that resembles a turtle shell, with deeply textured ribs arranged in a star-like formation. Unlike typical spiny cacti, the Kikko cultivar has a completely spineless surface covered in delicate white dots called areoles. It's considered a beginner to intermediate level plant, perfect for those new to cactus care or collectors seeking something different. Here's an interesting fact: the name 'myriostigma' comes from Greek words meaning 'countless spots,' referring to the thousands of tiny white flecks that give this cactus its frosted appearance.
FOLIAGE AND GROWTH HABIT
This cactus grows in a solitary, upright manner with a rounded to slightly columnar shape. The body is divided into five prominent ribs (though some specimens may have four or six), creating a distinctive star pattern when viewed from above. The surface texture is smooth and waxy, colored in soft grey-green to blue-green tones. The Kikko variation shows especially pronounced geometric ridging that creates a tessellated, almost architectural look. As it matures, the ribbing becomes more defined, enhancing the sculptural quality of the plant.
FLOWER DETAILS
The Bishop's Cap produces beautiful bright yellow flowers with orange or red centers that emerge from the top of the plant during spring and summer months. Each bloom measures about 5 to 6 centimeters across and has a daisy-like shape with numerous delicate petals. The flowers carry a light, pleasant fragrance that's subtle but noticeable up close. They typically last several days before fading. Flowering usually occurs once the plant reaches maturity, around three to four years of age. To encourage blooming, ensure the cactus receives a cool, dry winter rest period with reduced watering and plenty of bright light throughout the growing season.
CARE INSTRUCTIONS
🌞 Light: Bright, direct sunlight for 4-6 hours daily. Can tolerate partial shade but grows best with full sun exposure, especially morning light.
💧 Water: Water deeply but infrequently during spring and summer (every 2-3 weeks when soil is completely dry). Reduce to once monthly or less in fall. Keep almost dry in winter. Always water at the soil level, never from above.
🌡️ Humidity: Prefers low humidity between 10-30%. Thrives in typical dry indoor conditions.
🪴 Soil: Fast-draining cactus mix with added perlite or coarse sand. Soil must not retain moisture.
🏺 Potting: Shallow terracotta or clay pot with drainage holes. Pot should be slightly larger than the plant base. Repot every 3-4 years in spring.
🌱 Growth rate: Slow growing. Adds about 1-2 centimeters per year. Can reach 15-20 centimeters tall and 10-15 centimeters wide at maturity after 10-15 years.
👩‍🌾 Fertilizing: Feed monthly during spring and summer with diluted cactus fertilizer at half strength. No fertilizer in fall and winter.
🐾 Pet friendly: Yes, non-toxic to cats and dogs. The spineless surface makes it safer than most cacti, though the plant body itself should not be ingested.
WHERE TO PUT IT
The Kikko cactus does best on south or west-facing windowsills where it can soak up direct sunlight. It's ideal for bright living rooms, home offices, or sunrooms with plenty of natural light. Works well in modern or minimalist spaces where its sculptural form becomes a focal point. Also suitable for outdoor patios during warm months in most Canadian regions. Avoid placing it in dim corners, bathrooms with high humidity, or anywhere without access to several hours of direct sun. Keep away from cold drafts in winter and ensure it's not touching cold window glass during freezing temperatures.
