Additional Info
Plants that grow in both tidal and non-tidal habitats, such as this species will frequently show variations in their habit or growth-form. Plants that grow in tidal habitats will exhibit variations in leaf size and shape, leaf thickness, degree of branching, flower size, color of petals, and the degree to which flowers open, and they will often root at the nodes. Botanists have recognized many of these morphological differences, usually at the taxonomic rank of variety (Bidens frondosa var. anomala), however these distinctions are not clear and may only be an expression of tidal inundation, so taxonomic recognition may not be justified.
Habitats in which this plant occurs
