Like all pygmy sundews, it is able to reproduce asexually by producing gemmae in autumn.

[2] The plant has up to twenty active leaves, which are first semi-erect and then, when older, almost horizontal at the rosette's margin.

These have five white petals with a green section at the base, each up to 3.5 millimetres long.

[1] Drosera pedicellaris is part of the large group of the so-called "pygmy sundews", which form the genus' section Bryastrum.
