The Astrophytum myriostigma cv. Kikko nudum is a sought-after cultivar of the Bishop's Cap cactus, prized by collectors for its distinctive appearance. Unlike the standard species, this cultivar is spineless (nudum) and features prominent, undulating ribs that resemble a tortoise shell (kikko). It lacks the white flecks commonly found on the body of other Astrophytum myriostigma varieties, giving it a smooth, green surface.

Care Requirements

• This slow-growing, rare cactus is relatively easy to care for, provided it is given the right conditions. 
• Light
• Prefers bright, indirect light to partial shade, especially during the hottest parts of the day.
• Can tolerate full sun, but excessive midday heat and light can cause sunburn. 
• Water
• Follow the "soak and dry" method, allowing the soil to dry out completely between waterings.
• Water moderately during the spring and summer growing season.
• Dramatically reduce watering in the fall and keep the plant completely dry during the winter to prevent root rot. 
• Soil
• Requires a sharply drained, well-aerated soil mix to prevent root rot.
• A good mix is 60–80% inorganic material (like pumice, perlite, coarse sand, and crushed granite) and 20–40% organic material (like peat moss or fine bark).
• Ensure the pot has a drainage hole to allow water to escape easily. 
• Temperature
• Thrives in warm temperatures between 70–95°F (21–35°C) during the growing season.
• During its winter dormancy, it can tolerate cooler temperatures, but it is not frost-tolerant. Keep it in a dry, cool location (40–60°F / 5–15°C). 
• Fertilizer
• Fertilize sparingly with a low-nitrogen fertilizer during the spring and summer.
• Over-fertilizing can lead to leggy growth and damage the plant.

Propagation

The Astrophytum myriostigma cv. Kikko nudum is primarily propagated from seed, as it is a solitary cactus that does not produce offsets. 

1. Pollination: Cross-pollinate two plants to produce fertile seeds. Pollen from one flower is transferred to another using tweezers or a small brush.
2. Sowing: Sprinkle the seeds evenly over a well-draining, moist soil mix. Do not bury them.
3. Germination: Cover the pot with a clear lid or plastic bag to create a humid environment, and place it in a warm location with filtered light. Germination may occur within a few days to a few weeks.
4. Seedling care: Gradually introduce more ventilation as seedlings grow. Keep them protected from direct sun during the hottest hours. 

Distinguishing Features

• Star-like pattern: The genus name Astrophytum comes from the Greek words for "star plant," referring to the star-shaped patterns on some species.
• "Many dots": The species name myriostigma means "many dots," but the nudum variety lacks these markings.
• Spineless: The nudum (Latin for "naked") cultivar is spineless.
• Tortoise shell pattern: The Japanese name Kikko means "tortoise shell," a reference to the cactus's undulating, geometric ribs
