Leaves a basal rosette. Blades round, depressed, and lying flat on ground; ¼"-½" long and as wide or wider. Upper surface of blades covered with reddish, glandular hairs tipped with a sticky, glutinous secretion resembling a dewdrop that traps insects, hence its name. Petioles ¾"-2" long and covered with sticky hairs.
Roots usually shallow (less than 2½"), consisting of a taproot, functional for less than a year, replaced by mostly horizontal adventitious roots with a few root hairs.
Flower structure a one-sided raceme, with 2-15 flowers on a 2"-10" long stalk . There may be one to seven racemes per rosette.flowers which only open in the sunshine. Flower-stems erect, slender, 2 to 6" high, at first coiled inward bearing a simple raceme, which straightens out as flowers expand; these are very small and white, appearing in summer and early autumn.
Sepals 5, 4mm-5mm
Petals 5, white to pink; longer than sepals
