PlotAndPetal cannot tell you whether a plant you found can be eaten. Only someone who can see the plant can identify it.

Look-alike warning

Could be mistaken for Chamomile (Anthemis nobilis). To tell them apart: Feverfew is not chamomile.. ASPCA's 'Chamomile' page is Anthemis nobilis, a different plant.
