Flora of Railroad Yards

1910

It has been noticed that many plants not natives of the locality are to be found growing in the neighborhood of great railroad yards.

Sometimes the seeds of these plants have been brought thousands of miles from their natural habitat. Often they flourish amid their new surroundings and gradually spread over the surrounding country. Thus trains carry unsuspected emigrants, which travel to and from every point of the compass.

In the Mississippi valley are to be found plants which within a few years past have thus been brought together; some from the Atlantic seaboard, some from the gulf region, and some from the other side of the Rocky Mountains. — Harper's Weekly.
