haworthia truncata - Horse’s Teeth

Morphological Characteristics

Haworthia truncata is a distinctive and highly collectible succulent known for its unusual leaf structure and striking symmetry. Unlike most succulents that form rosettes, H. truncata grows in a fan-like, linear arrangement with fleshy, truncated leaves that emerge vertically from the soil.

Each leaf has a square or rectangular end with a flat, translucent “leaf window” that allows light to penetrate deep into the plant for photosynthesis. The surface texture is often mottled with green, gray, or brown patterns, creating a camouflage-like appearance.

Mature specimens grow slowly, forming tight rows of thick, chunky leaves that resemble horse teeth—hence the common name. It typically remains under 8 cm (3 inches) tall but can spread wider with age.

Growth Habits

This species is extremely slow-growing and prefers a stable environment with minimal disturbance. It typically grows as a single, non-offsetting clump but can produce pups at the base over many years.

Because of its compact size and architectural growth form, it is ideal for windowsills, bonsai-like arrangements, or display in shallow ceramic containers.

Maintenance Points

• Lighting: Prefers bright, indirect light or filtered morning sun. Avoid harsh midday sunlight, which can scorch the leaf windows.

• Watering: Water only when the soil is completely dry. Overwatering is the main cause of rot. Reduce water in winter dormancy.

• Soil: Requires a very well-draining mix—use cactus soil with added pumice or coarse sand.

• Temperature: Thrives at 18–27°C (65–80°F). Protect from frost; not tolerant below 5°C (41°F).

• Fertilization: Fertilize lightly during the growing season (spring/summer) with diluted succulent fertilizer.

• Handling: Avoid touching the leaf windows, as oils from fingers can damage their clarity and beauty.

• Pests: Rarely affected but watch for mealybugs and root rot in overly humid or wet conditions.

Display & Use

Haworthia truncata is a living sculpture, often showcased in:

• Minimalist, shallow planters with dark stone topdressing

• Japanese-style plant arrangements or dish gardens

• Succulent bonsai containers or indoor desk displays

• Collectors’ showcases due to its rarity and visual impact
