How to identify it

Pale grey body, often with a slight pinkish cast.
Subtle, sparse window markings.

vs. lookalikes: Within this group, use window pattern and marking style — body color shifts too much with light to be the sole identifier.

Care at a glance

Light	Very bright light — a south-facing window (in the northern hemisphere) with 4+ hours of direct sun, or a grow light delivering roughly 25,000–35,000 lux for at least eight hours a day. Too little light produces tall, soft, pale bodies.
Watering	Deep but infrequent watering during the spring and autumn growth windows; allow the substrate to dry completely between waterings. Withhold all water from the first sign of the spring molt until the old leaves are fully papery, and through the high-summer dormancy.
Soil	Free-draining mineral mix — roughly 70–80% inorganic grit (pumice, lava rock, akadama, or coarse perlite) with 20–30% sieved low-nutrient organic matter. The substrate should drain in seconds and dry within 48 hours.
Dormancy	Summer dormancy from roughly late June through August (in the northern hemisphere); a lighter winter rest from November through January. Plants in the southern hemisphere shift by six months.
Temperature	Comfortable between 10 °C and 28 °C. Tolerates short excursions from 5 °C up to 35 °C in cultivation. Avoid sustained frost and prolonged heat above 32 °C.
Repotting	Every 3–4 years in early autumn, before the second growth window begins. Use a deep pot (at least 10 cm) to accommodate the long contractile roots.

Growth & flowering

Like every Lithops, Lithops villetii runs on a single annual cycle: a winter-to-spring molt produces a fresh leaf pair, a short late-spring growth window rebuilds reserves, summer is a dry rest, and autumn brings a second growth window plus a single daisy-like white flower per mature head. Flowers open in the early afternoon, close at dusk, and repeat for a few days.

First flowering typically arrives at three to five years from seed. Established plants flower most years if the autumn watering window is clean — bone-dry through high summer, then deep waterings resumed in early autumn at roughly two- to three-week intervals. Skipping a year is normal; persistent non-flowering points to light, age, or a disrupted dormancy. For the genus-wide molting and watering walkthroughs, see our Guides.

Common problems

Stacked or 'tower' growth
Fix: Caused by watering during the molt. Stop water as soon as a new pair is visible in the cleft and resume only when the old leaves are completely papery and dry.
Etiolation — tall, soft, pale bodies
Fix: Not enough light. Move to the brightest window available or supplement with a grow light; increase intensity gradually over one to two weeks to avoid scorching.
Soft brown rot at the base
Fix: Overwatering combined with poor drainage or cool temperatures. Unpot, cut away rotted tissue with a sterile blade, callus the wound for several days, and replant in a much drier mineral mix.
Cracked windows after a deep watering
Fix: Usually a plant that dehydrated too far before watering resumed. Rehydrate with smaller, lighter waterings over several weeks rather than one big soak.
Mealybugs in the cleft or roots
Fix: Spot-treat with 70% isopropyl alcohol on a cotton bud every 5–7 days for three weeks. Inspect roots at the next repot — root mealybugs are common on Lithops and easy to miss.
