1.Drosophyllum — Overview
Drosophyllum lusitanicum, commonly known as the Portuguese sundew or Dewy Pine, is a distinctive perennial carnivorous plant indigenous to the arid, sandy, and often acidic coastal regions of southwestern Europe and North Africa, specifically Portugal, Spain, and Morocco. Unlike many of its carnivorous relatives, it thrives in dry, sunny, and open habitats with excellent drainage, demonstrating remarkable drought tolerance. This unique plant typically forms an upright, robust rosette, reaching 30 to 50 centimeters in height, with flowering stalks extending up to 60 centimeters. Its most striking features are its long, slender, linear-lanceolate leaves, ranging from 10 to 40 centimeters in length.
These leaves are densely covered with two types of specialized glandular hairs: stalked glands producing a highly viscous, glistening mucilage to ensnare insects, and sessile glands that secrete potent digestive enzymes. The leaves exhibit a unique spoon-like or channelled morphology, unfurling outwards from the central growth point in a phenomenon known as outward circinate vernation, a characteristic shared only with a few Byblis species. They typically display a vibrant green hue that can deepen to a striking reddish-purple under intense sunlight. The short, woody stem at the base supports the alternately arranged leaf rosette.
Its robust, though relatively shallow, root system efficiently anchors the plant in loose substrates and absorbs surface moisture. During summer, Drosophyllum produces elegant, bright yellow, star-like flowers, usually with five petals, borne on tall, erect stalks to avoid trapping pollinators. Taxonomically, Drosophyllum lusitanicum holds a singular position as the sole species in its genus, Drosophyllum, and the only member of the monotypic family Drosophyllaceae, distinguishing it from the more widespread Droseraceae family and highlighting its evolutionary distinctiveness.

6.Drosophyllum — Water Requirements
- ✓ Substrate Preparation — Use a well-draining, arid-mimicking mix, typically Cornish grit with a small amount of coarse peat moss to retain minimal moisture.
- ✓ Potting — Utilize large, deep containers (e.g., 10-liter plastic pots) to accommodate its substantial root system, crucial for long-term health.
- ✓ Light Requirements — Provide full sun exposure; outdoor cultivation during summer encourages compact growth and robust health.
- ✓ Watering — Water sparingly; allow the substrate to dry out significantly between waterings, mimicking its natural dry habitat. Only water during exceptionally dry spells.
- ✓ Temperature and Frost — Protect from hard frosts; move plants to a frost-free location (minimum 7°C) during cooler months, though light frost may cause minimal damage.
- ✓ Propagation by Seed — Seeds are viable for long periods (even years if refrigerated) and germinate easily. Sow single seeds 5mm deep in small fiber pots in a 50:50 peat moss and silver sand mix, standing pots in rainwater in full sun.
- ✓ Germination and Transplanting — Expect germination in 4-6 weeks. Transplant seedlings approximately 6 cm tall into larger containers to allow root development.
- ✓ Air Circulation — Good air circulation is beneficial to prevent fungal issues, especially in humid environments.
