Origin of Name

Haworthia cv. 'Black Obtusa' is a cultivated variety (cv) within the Haworthia genus. The name 'Black Obtusa' likely refers to the dark coloration of the leaves and the obtuse, or rounded, shape of the leaf tips. This name sets it apart from other Haworthia cultivars with different coloration and leaf shapes.

Technical Description of Plant

Haworthia 'Black Obtusa' is a small, rosette-forming succulent known for its striking appearance. It usually grows to about 3-5 inches in height and diameter. The rosette is composed of thick, fleshy, dark green to almost black leaves that are smooth and glossy. The leaves are broad at the base and taper to rounded tips, which are often translucent. The dark coloration of the leaves, especially under direct sunlight or stress conditions, is a distinguishing feature of this cultivar. While it does bloom, the flowers are typically small and white, appearing on thin, elongated stalks.

Origin of Plant

The Haworthia genus is native to South Africa, and 'Black Obtusa' is a result of selective breeding and cultivation, primarily for its unique color and form. These plants are adapted to semi-arid climates and typically grow in rocky or sandy soils.

Conservation Status

As a cultivated variety, Haworthia 'Black Obtusa' does not have a specific conservation status. However, the cultivation of these plants helps in reducing the demand for wild-collected specimens and supports the conservation of Haworthia species in their natural habitats.

Care Instructions

Haworthia 'Black Obtusa' is relatively easy to care for, making it suitable for beginners. It prefers bright, indirect light but should be protected from harsh, direct sunlight, which can cause leaf burn. A well-draining soil mix is crucial, and the plant should be watered moderately, allowing the soil to dry out completely between waterings. In winter, reduce watering to a minimum. 'Black Obtusa' is not frost-tolerant and should be kept in a temperate environment. Fertilization is not essential, but a diluted succulent fertilizer can be applied sparingly during the growing season.
