Droseraceae is a family of carnivorous flowering plants, also known as the sundew family. It consists of approximately 180 species in three extant genera, the vast majority being in the sundew genus Drosera. The family also contains the well-known Venus flytrap and the more obscure waterwheel plant, both of which are the only living species of their respective genera. Representatives of the Droseraceae are found on all continents except Antarctica.
Many carnivorous plants like sundews and pitcher plants need a cold winter rest before their seeds will sprout, and this study looks at how long that chilly period needs to last as winters grow warmer and less predictable. The findings matter because a shorter or inconsistent cold season could make it harder for these plants to regenerate naturally in the wild.
