Polygonaceae

Leaves grow basally, and are two to three feet long, deeply palmately lobed. Tiny white, pink, or reddish flowers have a six-part calyx, no petals, and bloom in panicles on tall, branched stems. Fruits are three-sided, white, pink, or rust-colored, quite longlasting, and are perhaps more interesting than the flowers.
