Herbs/Forbs

Herbaceous plants ("herbs") are vascular plants without significant woody tissue above or at the ground and include flowering plants, ferns, horsetails, lycopods, and whisk-ferns. They may be annual, biennial, or perennial but always lack significant thickening by secondary woody growth and have perennating buds borne at or below the ground surface. Forbs are non-graminoid (grasses, sedges, rushes, etc.) herbaceous plants and represent a guild of plant species with broadly similar growth form, which in ecology is often more important than taxonomic relationship. The following species have been reported to be invasive in natural areas in the U.S. Species native to the U.S. are included when they are invasive in areas well outside their known natural ranges, as a result of human activities. For more information on each species, including the listing sources, images, and distribution maps, click on the species.
