Plant Information Online offers a collection of databases of interest to plant and gardening enthusiasts and students, as well as professional botanists, horticulturists, and researchers. Some of the databases have been available in print (various titles) since 1979 and online through paid subscription since 1997. The whole site is now available free to the general public.
