The Wood Anenome greets the oncoming spring with its numerous white flowers. This species lacks any indication of a UV floral pattern, however. This sharply contrasts the strong UV signature of its close relative, Yellow Anemone (A. ranunculoides).

In common with other spring-flowering species, such as Hepatica nobilis, in this family, A. nemorosa displays quite strong reflectance in near-IR. Thus, the venation pattern of the petals stands out very strongly in this spectral band.
