Filipendula ulmaria - Hardy herbaceous perennial. 60-80 cms, 60 cms width. Full sun to part shade. Clusters of creamy white flowers in the summer and autumn. Flowers and leaves sweetly aromatic. Soft fern like green foliage In the wild it grows near streams, rivers, damp meadows, marshlands and wet woodlands, so in the garden it requires a moisture retentive soil, with added well rotted manure and a good layer of mulch.  A good spring tonic for farm animals. Particularly well liked by goats and sheep.  A black dye can be made from the roots, a yellow dye from the flowers and a blue dye from the leaves and stems. A frost hardy plant. Along with water mint and vervain, meadowsweet was one of the most sacred of herbs to the ancient druids.
