Venus Flytrap King Henry
IntermediateDionaea muscipula 'King Henry'
A Venus Flytrap cultivar with tall upright traps giving a kingly, powerful appearance.
Overview
King Henry (Dionaea muscipula 'King Henry') is a Venus flytrap cultivar notable for its strongly erect, upright leaf habit, with traps held high above the substrate rather than spreading flat as many cultivars do. This regal, vertical posture—reminiscent of a monarch holding court—is the origin of its name. The upright growth makes it particularly striking in pot culture and distinguishes it visually from most other cultivars. The snap-trap mechanism is identical to the wild species. Adult plants can reach 10–18 cm in diameter, making it one of the larger cultivars.

Growing Tips
Light & Placement
Grow it in strong direct sun. Its upright leaves rise tall, so place it outdoors in full sun where nothing shades it.
Watering
Tray-water to keep it constantly moist, using only pure or rain water. Minerals in tap water build up and weaken the plant.
Soil & Repotting
Use pure sphagnum or peat moss with perlite, and never fertilize. A large cultivar reaching 10-18 cm across, it needs a deeper pot.
Dormancy Care
Let it go dormant at 5-10°C in winter. The upright leaves may die back, but the bulb lives; keep the tray shallow and wait for spring.
Pests & Cautions
Traps close only a limited number of times, so do not trigger them for fun. The tall leaves are easily damaged by wind, so ventilate but avoid strong gusts.
