Drosera prolifera vs. D. anglica & D. filiformis: Light Needs Differ

Drosera prolifera thrives in partial sun (3–4 hours direct + reflected light), while D. anglica and D. filiformis require full, all-day sun to produce dew. If your temperate sundews lack dew, move them outdoors.

Why the Difference?

• D. prolifera is a tropical/subtropical species from Brazil, adapted to shaded, humid conditions.
• D. anglica & D. filiformis are temperate North American natives that evolved in open bogs with intense sunlight.

Action Plan

• Keep D. prolifera in its current bright window (NE exposure, 70s°F day/60s°F night).
• Move D. anglica and D. filiformis outside to full sun immediately.
• Use 1:1 peat/perlite for all; keep in water trays with pure water.

Dew production is a direct indicator of light adequacy. No dew = not enough sun for temperate species.
