Examples include St. Peter's wort, a four-petaled, yellow flower on a shrubby plant, up to three
feet tall; St. John's wort, a similar flower, with five petals, and penny wort, with creeping stems,
small round leaves and small, pink-tinged blossoms, also yellow-eyed grass, characterized by a
leafless, flowering stem, and yellow, round heads at the end of a short spike; pipe wort, its small
flowers forming a white, gray or brown button-like head at the top of fluted stems; marsh pines,
consisting of four to 12-lobed flowers of pink, white, or blue; and fog fruit, growing small blue
flowers on a low, compact stalked head. Colic root, topped by small, tubular, yellow flowers,

Arrow-head is a white aquatic flower, in whorls of three. The beautiful spider lily, with a
