Any of various plants with flowers that resemble a crow in shape or color, or that are known to attract crows; a wildflower associated with fields where crows gather.
From 'crow' (the bird) + 'flower' (a bloom). This descriptive compound emerged in regional or folk botany, naming plants by their visible characteristics or bird associations.
Folk plant names often reveal what people observed: if crows loved a flower's seeds or if the petals looked crow-colored, farmers would simply call it a 'crowflower,' preserving ecological knowledge in vocabulary.
