Cathedral Window Haworthia (Haworthia cymbiformis var. obtusa), also known simply as Haworthia obtusa, is a beautiful and unique succulent known for its translucent leaf tips that resemble stained glass windows, hence the name “Cathedral Window.” This charming plant is native to South Africa and is highly sought after by succulent enthusiasts for its attractive rosette form and striking appearance.

Key Characteristics:

• Leaves: The leaves of Cathedral Window Haworthia are thick, fleshy, and slightly curved, forming a compact rosette. The most distinctive feature of this plant is the translucent, almost glassy “windows” at the tips of the leaves, which allow sunlight to filter through and help the plant photosynthesize. The leaves are typically a pale green or blue-green color and may take on a slight pinkish hue in bright light or during stress.
• Growth Habit: Cathedral Window Haworthia forms small, compact rosettes that typically grow to about 3-4 inches (7-10 cm) in diameter. The plant has a slow growth rate, making it an excellent choice for small spaces, containers, or as part of a succulent arrangement.
• Flowers: In the spring or summer, Cathedral Window Haworthia may produce small, white or pale pink, tubular flowers on tall, slender stems. While the flowers are not particularly showy, they add a delicate touch to the plant’s overall appearance.

Care Tips for Cathedral Window Haworthia (Haworthia cymbiformis var. obtusa):

1. Light:
   • Cathedral Window Haworthia prefers bright, indirect light. It can tolerate some direct sunlight, particularly in the morning or late afternoon, but too much intense sunlight can cause the leaves to become sunburned. If grown indoors, place it near a bright window with filtered light. In lower light conditions, the plant may lose some of its vibrant color and become more green.
2. Watering:
   • Water the plant sparingly, allowing the soil to dry out completely between waterings. Cathedral Window Haworthia is drought-tolerant and prefers to be kept on the dry side. Overwatering can lead to root rot, so it’s important to let the soil dry out before watering again. During the growing season (spring and summer), water the plant regularly, but reduce watering in the fall and winter when the plant’s growth slows down.
3. Soil:
   • Use a well-draining cactus or succulent soil mix. You can improve drainage by adding perlite, pumice, or coarse sand to the soil. Proper drainage is crucial to prevent root rot and keep the plant healthy.
4. Temperature:
   • Cathedral Window Haworthia prefers temperatures between 65-80°F (18-27°C) during the growing season. It can tolerate cooler temperatures down to around 50°F (10°C) but should be protected from frost. If grown outdoors in cooler climates, bring it indoors when temperatures start to drop.
5. Fertilizing:
   • Fertilize the plant once a month during the growing season with a diluted, balanced fertilizer formulated for succulents. Avoid fertilizing during the winter months when the plant’s growth slows down.
6. Propagation:
   • Cathedral Window Haworthia can be easily propagated by removing offsets or “pups” that form around the base of the mother plant. To propagate, gently separate the offsets from the main plant and allow them to callous over for a day or two before planting them in well-draining soil. The offsets will quickly establish roots and grow into new plants.
7. Pests and Diseases:
   • Cathedral Window Haworthia is generally resistant to pests but can occasionally attract mealybugs or aphids. Regularly inspect the plant and treat any infestations with insecticidal soap or neem oil. Be cautious of overwatering, which can lead to root rot and other fungal issues.
