Alice sundew

Alice sundew (Drosera aliciae) is a perennial carnivorous plant species belonging to the family Droseraceae. In a horticultural context, it is highly regarded for its aesthetic value and unique biological adaptation, which allows it to thrive in nutrient-poor environments by trapping small insects.

The plant originates from the Cape provinces of South Africa. Its natural habitat includes damp sandy soils and swampy areas. In cultivation, it requires conditions that mimic these bogs, making it a staple crop for specialized greenhouses and indoor plant collections worldwide.

Botanically, Drosera aliciae forms a basal rosette of wedge-shaped leaves. These leaves are covered in stalked glands that produce a sticky, glistening mucilage used to capture prey. Once an insect is trapped, the leaf slowly curls around it to secrete digestive enzymes and absorb nutrients.

Agronomic requirements are strict: the plant needs a nutrient-poor medium, typically a mix of peat moss and perlite. Fertilizer is strictly prohibited as it can chemically burn the sensitive root system. Irrigation must be performed exclusively with distilled, reverse osmosis, or rain water to prevent mineral buildup.

• Light: High levels of bright, indirect sunlight or artificial grow lights.
• Watering: Tray method, keeping the base of the pot in 1-2 cm of water.
• Dormancy: Minimal, though growth may slow down during the winter months.

Typical pests include aphids, which may cluster on the flower stalks, and mealybugs if humidity is kept too low. Fungal infections can occur if there is insufficient air circulation or if the potting medium becomes waterlogged and stagnant. Maintaining a clean, well-ventilated growing environment is essential for disease prevention.
