A photographic triptych showing seed dispersal from the seed heads of a great willowherb. As plants have very limited mobility, they rely upon a variety of dispersal vectors to transport their seeds. Seeds may be dispersed individually or collectively. Some plants are serotinous and only disperse their seeds in response to an environmental stimulus. There are five main modes of seed dispersal: gravity, wind, ballistic, water, and animals. Photograph: Colin Recently featured:
