Trout lily (Erythronium americanum) exhibits striking variation in the colour of its anthers & pollen grains. Anthers that lack red pigment are pure yellow in color, whereas those that produce red pigment range in color from pale orange to deep brick red. Although this variation is well known, its ecological significance remains virtually unstudied.
The goal of the Trout Lily Project is to document the frequency of the yellow and the red-orange anther morphs across the range of American trout lily (Erythronium americanum). If you’re out admiring the spring ephemerals this year, please take a closer look at the trout lilies, and submit your observations here.
A big thank you to the nearly 100 citizen scientists who submitted data during 2016. You can find a summary of last year’s results here.
