[cite:1124720 ]

The PLANTS Database provides standardized information about the vascular plants, mosses, liverworts, hornworts, and lichens of the U.S. and its territories.

It includes names, plant symbols, checklists, distributional data, species abstracts, characteristics, images, crop information, automated tools, onward Web links, and references.

This information primarily promotes land conservation in the United States and its territories, but academic, educational, and general use is encouraged.

PLANTS is a collaborative effort of the USDA NRCS National Plant Data Team (NPDT), the USDA NRCS Information Technology Center (ITC), The USDA National Information Technology Center (NITC), and many other partners.
