Hundreds of plant species are blooming in winter across the UK, alarming scientists.
Researchers say the phenomenon is a visible sign of climate breakdown.
Data from the annual New Year Plant Hunt show warmer winters are shifting plant cycles.
An analysis by the Met Office links higher temperatures to increased winter flowering.
For every 1C rise in late-autumn temperatures, 2.5 more species bloom in winter.
In 2025, volunteers recorded 310 native plants in flower.
That figure far exceeds the usual expectation of around 10 species.
Including non-native plants, 646 species were found flowering.
The Botanical Society of Britain and Ireland called the trend a clear climate warning.
Common daisies and dandelions are among plants now flowering out of season.
Scientists warn rising temperatures are disrupting ecosystems nationwide.
