Triggering Gemmae Production in Drosera scorpioides

Drosera scorpioides produces gemmae (asexual propagules) in late autumn in response to shortening day length. If grown under artificial lights, reduce the photoperiod to 10 hours/day for a month to simulate autumn.

Plants near a window will naturally initiate gemmae as days shorten. In the Pacific Northwest, we typically see gemmae in late November.

Once gemmae form, harvest and sow them on moist peat:sand mix. They'll develop into mature plants over the next year. This is the primary propagation method for pygmy sundews.

Key Point: Photoperiod, not temperature, is the main trigger. Adjust your lights accordingly to get reliable gemmae crops annually.
