Late Summer Browning in Hybrid North American Sundew: Normal Dormancy Onset

A grower's sundew (awesome all summer, heavy flowering, great bug catcher) shows browning in late summer. Asks if problem or seasonal.

Jeff Dallas: Plant appears to be D. intermedia × D. filiformis (D. × hybrida). Late summer scrappiness is normal—many North American sundews enter dormancy as September approaches.

Hybrid vigor doesn't eliminate dormancy requirement. Temperate sundews must rest. Reduce watering slightly, allow natural dieback, keep cool and bright through winter.
