The tip of the stem of redroot amaranth produces a panicle of greenish-white flowers; smaller panicles of flowers also arise from the axils of the leaves in the upper half of the plant. Both male (staminate) and female (pistillate) flowers appear in the same inflorescence; perfect flowers are absent. Individual flowers lack petals but have 5 white tepals that are about 3 mm long and one or more small (3-6 mm) green, bracts under the flower whose midrib extends to form a spine; male flowers also have 3-5 yellow stamens, while female flowers also have an ovary with a 3-parted style on the top of the ovary.

About

I want to acknowledge the work of a friend and colleague, Dr. Fred Donner. We both share a passion for the flowers in Jackson Park. Fred's website (jacksonparkwildflowers.org) inspired me to build my own website and database; use and enjoy them both.

I am also pleased to thank my ninja web gurus and coders, Lindsey Young and Stefanie Engstrom. This site would not exist without their herculean labors.
