Drosophyllum Seed Production and Cold Weather Care

Drosophyllum lusitanicum (dewy pine) sometimes produces empty seed pods despite flowering. Cross-pollination between different flowers—or ideally, different plants—significantly improves seed set compared to self-pollination. Using a small brush to transfer pollen between flowers mimics natural insect pollination and yields better results.

Regarding cold tolerance: Drosophyllum and Drosera regia should not be moved outdoors until nighttime temperatures consistently stay above freezing. In climates similar to the Pacific Northwest, April is typically safe. While these plants can handle light frosts, prolonged exposure to temperatures around 30°F (-1°C) risks damage, especially to young plants.

Wait for stable spring conditions before transitioning them outside. A cold frame or protected location can help during the transition period.
