Haworthia cymbiformis

Cathedral Window Haworthia (Haworthia cymbiformis)

Haworthia cymbiformis is an endearing, stemless rosette succulent native to the Eastern Cape of South Africa, famous for its boat-shaped, pale green leaves. The translucent leaf tips, often called leaf windows, evolved to channel ambient sunlight into the deeper subterranean photosynthetic tissues while shielding the plant from harsh heat. It readily clusters via basal offsets, forming lush, dense cushions ideal for compact indoor collections.

📋 Core Botanical Care Parameters

☀️ Light Requirements

Bright, indirect or dappled light is optimal. Avoid intense, direct afternoon sun, which can scorch leaf tips and cause reddish-brown stress coloration, while inadequate light leads to etiolation.

💧 Watering Frequency

Use the 'soak-and-dry' method. Allow the substrate to dry out thoroughly between waterings, and reduce watering significantly during the cool winter dormancy to prevent root rot.

🏺 Soil Mix

60% porous mineral grit (pumice, lava rock, perlite) + 40% organic cactus potting soil.

❄️ Cold Tolerance

-1°C (USDA Zone 10a)

🌱 Propagation Method

Basal offset division (pups), leaf pullings, or seeds.

🐾 Pet Safety

This plant is non-toxic to cats and dogs and safe for pet-friendly homes.
