White trillium, Trillium grandiflorum.

Populations of white trilliums (Trillium grandiflorum) do not expand rapidly because the seeds are dispersed over small distances by insects and mammals. When the berry-like capsules are mature, they open and slowly discharge their seeds. Attracted by an oily appendage on the seeds, ants take the seeds to their nests. Mammals such as chipmunks that take the fruit thereby also help disperse the seeds. Common yellow jacket wasps also consume the fruit, so they may be a secondary agent of dispersal.
