Single-Flowered Bladderwort problems — and how to fix them
Single-Flowered Bladderwort (Utricularia uniflora) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Overheating in summer
U. uniflora originates from cool-temperate Australian coastal and Tasmanian habitats. Temperatures above 28°C cause stolon dieback and failure to resprout. Grow in the coolest available position, and avoid south-facing windows in summer in the Northern Hemisphere.
Disappearing plant — dormancy misidentified as death
The plant can reduce to barely visible stolon fragments during cooler months or dry spells, appearing to have died. Do not discard the pot — keep it moist and cool, as growth reliably resumes in spring when temperatures rise and day length increases.

Most single-flowered bladderwort issues are care-mismatch, not bad luck. Dial in the basics:
