Aerangis alcicornis

Aerangis alcicornis is a miniature epiphytic orchid belonging to the Orchidaceae family. Known for its distinctively shaped white flowers that resemble stag horns—hence the name "alcicornis"—this species is highly prized by orchid enthusiasts for its elegant structure and intense evening fragrance.

The plant originates from the tropical forests of Madagascar. In its native habitat, it grows as an epiphyte on tree branches, thriving in humid environments with dappled sunlight. This adaptation allows the plant to access moisture from atmospheric humidity and fog, which is a critical factor to replicate in home cultivation.

Botanically, Aerangis alcicornis features short stems and thick, leathery, dark green leaves. The roots are thick and photosynthetically active, which is essential for nutrient uptake in epiphytic conditions. The flowers are typically arranged in pendulous racemes, showcasing the unique spur morphology typical of the genus.

The cultivation requirements focus on mimicking high-humidity tropical conditions. It is best grown mounted on cork bark or tree-fern slabs to ensure optimal airflow to the roots. Temperatures should be kept stable between 18°C and 24°C, and the plants require frequent misting while avoiding standing water on the foliage to prevent rot.

The primary use of this species is in the specialized hobbyist market and botanical conservatories. Like many orchids, it is susceptible to pests such as mealybugs and scale insects. Maintaining good hygiene and proper ventilation is the most effective defense against diseases like bacterial leaf spot and various fungal rots.

• Maintain high ambient humidity levels.
• Provide bright, indirect light exposure.
• Use mounted cultivation for root aeration.
• Apply dilute orchid fertilizers during the growing season.
