Alpine sundew - Drosera arcturi (Taxonomy, Characteristics, Flower, Images)

Alpine sundew

The leaves of Drosera arcturi are linear, 1 to 5 cm long, undivided, and range in colour from pale green to muddy brown, to maroon if subjected to full sunlight. Young leaves begin at the center of the plant and are folded along their center. After two or three leaves have formed, the nominal form produces a small, solitary white flower, 1.3 cm across, which is borne on a short stalk in summer, and positioned near the top of the leaves. The giant, lowland form produces 1–5 flowers on a long inflorescence up to 25 cm long.

Water: Alpine sundew thrives in high humidity and consistently moist environments, favoring damp conditions. Watering twice a week is essential to maintain soil moisture, and additional misting can replicate its natural wet habitat. It is adapted to outdoor boggy terrains with regular rainfall.

Pruning: Alpine sundew, a carnivorous plant with vibrant, insect-trapping leaves, requires pruning of dead foliage in early to late spring for optimal health and new growth. Use sterilized scissors to prevent infection. Regular maintenance keeps alpine sundew attractive while maintaining a moist, acidic environment.

Propagation: Alpine sundew is an insectivorous perennial that thrives in wet, alpine environments, using sticky leaves to capture prey. Propagation is achieved through division of mature rosettes during active growth, requiring careful handling to protect roots. Plant divided sections in a well-draining, sphagnum peat-based medium, ensuring high humidity.

Repotting: Repot alpine sundew every 2-3 years in spring using a slightly larger pot for root growth. Post-repotting, ensure bright, indirect light and high humidity for recovery, as alpine sundew prefers moist conditions. Handle gently to support the delicate nature of its carnivorous leaves.
