A forb (sometimes spelled phorb) is a herbaceous flowering plant that is not a graminoid (grasses, sedges and rushes). The term is used in biology and in vegetation ecology, especially in relation to grasslands[1] and understory.

"Forb" is derived from Greek Φορβη (phorbe), "pasture" or "fodder".[2][3] The spelling "phorb" is sometimes used, and in older usage this sometimes includes graminoids and other plants currently not regarded as forbs.
Forbs are members of guilds of plant species with broadly similar growth form. In certain contexts in ecology guild membership often may be more important than the taxonomic relationships between organisms.
In addition to its use in ecology, the term "forb" may be used for subdividing popular guides to wildflowers, distinguishing them from other categories such as grasses, sedges, shrubs, and trees.
Some examples of forbs are clover, sunflower and milkweed.
