Drosera hilaris: Winter-Growing South African Sundew

In cultivation: grows actively under lights in a cool greenhouse (50–65°F) in winter. Growth nearly stops in summer heat—it doesn't die back completely like D. cistiflora, but pauses. Keep barely moist during the summer rest period. Resume watering and feeding in autumn as temperatures drop.

Treat it like other winter-growing Cape sundews: well-draining sandy mix, bright light, cool temperatures. A fascinating addition for growers who can provide seasonal cues.
