Native to US. Found in full to partial sun; moist to dry; open woods, meadows and fields. The fruit capsule holds three seeds, probably giving the plant its common name. I first noticed the plant last year when I began to have signs of allergies and looked around for the culprit. Turns out, it is known to have mild allergens when pollination occurs during summer to fall, depending on location.
