This study investigated the impact of climate warming on the flowering phenology of 36 plant species in eastern Pennsylvania using herbarium specimens collected from 1884-2015. The researchers analyzed the relationship between annual, winter, and spring temperatures and flowering time, considering plant functional traits like native status, growth habit, fruit type, and blooming season. Results showed that plants flowered earlier with increasing annual and spring temperatures, but winter temperatures had no significant effect. The response to warming varied among species, with spring-blooming species showing a greater response than summer-blooming species.
