From Small Seeds Grow BIG Dreams

Getting Around

The ground would get crowded if all of a plant's seeds sprouted beneath it. But that rarely happens. Plants have wonderful ways of moving their seeds to new places.

2. Water. American elm seeds can float for miles after falling into a stream.

graphic: Plant Power moving seeds.4. Plant power. In warm weather the seed pods of witch hazel, a forest shrub, burst open and fling seeds far from the parent plant. Dwarf mistletoe, which grows on evergreens, can shoot its seeds 20 feet at almost 60 miles per hour.

graphic: Animal insides carrying seeds5. Animal insides. When birds, bears, or other animals eat fruit, they unknowingly move the seeds inside their bodies. The seeds end up in a pile of the animal's droppings in a new place. The droppings fertilize the new plant.

Some seeds have claws, spines, hooks, or other parts that cause them to cling to animals passing by. After falling off or being pulled off the animal, the seeds can sprout in a new place.

If these seeds are from fast-spreading plants such as dandelions or garlic mustard that aren't native to Minnesota, they can crowd out native plants.
