A spineless, dome-shaped cactus dotted with white speckles, staying the size of a small bun — ideal for a sunny windowsill or tabletop.
Light ExposureinfoIndoor light recommendation based on the plant's native habitat. "Bright indirect" means near a window but shielded from direct rays.
Direct Sun Tolerant — Provide appropriate light conditions.
Watering HabitinfoHow forgiving this plant is when you miss a watering or accidentally overwater. High tolerance means more room for error.
High — Water when soil surface is dry.
Maintenance DifficultyinfoOverall ease of care rating. Beginner-friendly plants communicate their needs clearly through visible signs.
High — Great for beginners. Communicates needs clearly.
Spatial RequirementinfoExpected mature size in a typical indoor environment. Actual size depends on light, pot size, and growing conditions.
Compact — Best for Living Room.
Seasonal BehaviourinfoHow this plant's growth changes with the seasons. Use this to adjust your care routine throughout the year.
Warm Season Only — Thrives in heat. May go fully dormant when temperatures drop. Drops all leaves in its off-season — this is normal, not a danger sign.
Temperature NeedsinfoThis range represents the plant's survival tolerance. Optimal growing temperatures are typically 5-10°C higher than the minimum.
4.4°C – 35°C — Cool-Tolerant — Standard indoor is warm enough. Tolerates cooler rooms — no special heating needed.

Let the soil dry out almost completely before watering again. When in doubt, wait two more days.
Can handle direct sunlight, but introduce it gradually over a week to prevent leaf burn.
Go for a chunky, open mix — think orchid bark, perlite, and a bit of horticultural charcoal. Avoid dense, peat-heavy soils.
Happy in cooler rooms — anywhere between 4.4–35°C is fine. Avoid placing near radiators or heat vents. No humidity concerns — normal indoor air is perfectly fine.
This is a slow grower — it won't outgrow its spot anytime soon, so enjoy it as-is and mostly takes care of itself. Just remove the occasional yellow leaf.
What Makes It Special
Spineless, disc-shaped flattened globose cactus 2.5–6 cm tall × 5–15 cm in diameter, divided into typically 8 ribs (7–10) dotted with white woolly trichome tufts forming a speckled sand-dollar appearance; greenish-brown body completely smooth and spineless, safe for homes with pets
