Drosera filiformis, commonly known as the Thread-leaved sundew,^[1] is a small, insectivorous, rosette forming species of perennial herb. A species of sundew, it is unusual within its genus in that the long, erect, filiform (thread-like)^[1] leaves of this plant unroll in spirals - an arrangement similar to the circinate vernation seen in Ferns.

[edit] Distribution and habitat

D. filiformis occurs naturally in both Canada and the United States; it's natural range extends down the eastern seaboard of North America from south western Nova Scotia^[1] in the north down through New England to Florida and Louisiana in the south.
