bright indirect light (3-6 feet from a south or west window, or right next to an east window. Under a grow light, 6-10 inches away works well) is ideal indoors. It tolerates some direct morning or late afternoon sun but not harsh midday exposure. In its natural habitat it lives in the shade of low shrubs, so err on the side of protection.Light
Soak and dry: water thoroughly (water until it drains out the bottom. Empty the saucer after 30 minutes so the roots are not sitting in water), then wait for the soil to dry completely. water sparingly (water small amounts, less often. Let the soil dry out almost completely between waterings) in summer (semi-dormancy) and winter. Overwatering is the most common cause of loss. Use the soak-and-dry method consistently.Water
Tolerates low humidity typical of most homes. Avoid high humidity (60-80%. Group your plants together, set them on a pebble tray with water, or run a humidifier nearby) combined with poor airflow, which promotes rot.Humidity
Thrives at 60-80°F (15-27°C). Can handle brief light frost to around 23°F (-5°C) in very dry soil, but frost protection is recommended. Hardy in USDA zones 9a-11.Temperature

Haworthia truncata plant

Clipped Window Plant

Haworthia truncata

Moderate

Haworthia truncata is one of the plant world's true oddities: its leaves are arranged in two flat rows like a hand of cards, each one appearing to have been sliced straight across at the tip, leaving a flat translucent window exposed to the sky. In the wild it grows almost entirely underground, with only those windowed tips visible at the surface, collecting light while staying hidden from browsers and the scorching Karoo sun. You might keep it for years before a visitor notices what it is, and the explanation is always worth the pause.
