Slender Yelloweyed Grass

Xyris torta (ZY-riss TOR-tuh)

Family: Xyridaceae Unknown Herbaceous (1-3 ft)

Xyris torta is a short-lived perennial that grows from a deeply rooted, chestnut-brown bulb. The yellow flowers typically bloom one or two at a time, so not very showy. The small blooms appear at the tip of the stem with many scale-like bracts that spiral around the head. A single flower will emerge from each bract. In the center of each flower is 3 erect, fertile, yellow stamens and 3 hairy, sterile stamens. The bracts will remain, forming a seed head that will expand as the fruit matures. It can be found growing in wetlands such as bogs, marshes, wet ditches and shores of rivers or lakes.
