Marsh bellflower is a strange little native plant that doesn't look like a bellflower at all. Needle-like leaves grow along thin, sprawling stems that lie across other plants in moist prairies. It resembles Sprenger's asparagus. The leaves have a prickly feel like Galium aparine. In late summer, tiny five-petalled cupped flowers appear. The petals are white, with a thin lavender-blue line down the center. The flowers have long pedicels (stalks) and are solitary or in small clusters.
