Sundews tend to grow on the edges of bogs and streams, in waterlogged conditions, on acidic peaty soils. Since this type of soil is very low in nutrients, the plant supplements its mineral requirements by trapping and digesting insects. The leaves are covered in long hairs; at the end of each hair is a ball of glistening sticky goo which entraps insects, after which the leaves close around the insect to digest it.
The white flowers are borne on an erect slender stem, and often do not fully open.
This species is similar to the Oblong-leaved Sundew, differing in the shape of its leaves and the length of its flower stalk.
