Soft Rush
The rushes are grass-like, usually perennial, clumping plants that, despite their appearance, are more closely related to the lilies than grasses. Because they closely resemble the grasses and sedges, soft rushes are often confused with them. They are separated from the grasses by the technical aspects of the flowers and the absence of a ligule (a membrane-like projection) where the leaf blade joins the sheath. Not all species of rushes have leaf blades, but instead have a leaf sheath. The flowers are terminal, but in some species the flowers appear to be on the side of the plant because an upper erect leaf looks like a continuation of the stem.
