# 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.

## Light & Sun Exposure

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 Schedule & Method

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 & Gritty Mix Formula

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

## Cold Tolerance & Overwintering

-1°C (USDA Zone 10a)

## Propagation Methods

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