Meadowsweet Vulgaris Seeds
Filipendula vulgaris
Also known as Fernleaf Dropwort. Clusters of creamy-white sweet-scented flowers top very thin, strong stems, making them look like they are suspended in the air. The fern-like foliage makes this a very ornamental herb for the garden. Contains  salicylic acid, the active component of aspirin, and the leaves and roots are a source of methyl salicylate, or oil of wintergreen. 
Young leaves and roots can be cooked or eaten in salad, with a bitter, wintergreen flavor.
