Changes in flowering times due to climate change have led to longer flowering durations for plant species in central North America, averaging an increase of 11.5 days over the past century.
Nearly all species studied (94%) showed greater overlap in their flowering periods, particularly in autumn, where late-season species have extended their blooming periods.
This research highlights the significant impact of climate change on plant reproductive patterns, suggesting that the effects are more pronounced in certain seasons, like autumn.
The long-recognized genus Gaura was shown recently to be deeply nested within one of two major clades of Oenothera. New molecular data indicate further taxonomic changes are necessary in Oenothera sect. Gaura.
