Facts
Seaside plantain is native to mainly coastal habitats throughout the northern hemisphere. The young leaves can be eaten raw or cooked.
Habitat
Brackish or salt marshes and flats, cliffs, balds, or ledges, marshes, ridges or ledges
New England distribution
Adapted from BONAP data
Native: indigenous.
Non-native: introduced (intentionally or unintentionally); has become naturalized.
County documented: documented to exist in the county by evidence (herbarium specimen, photograph). Also covers those considered historical (not seen in 20 years).
State documented: documented to exist in the state, but not documented to a county within the state. Also covers those considered historical (not seen in 20 years).
Note: when native and non-native populations both exist in a county, only native status is shown on the map.

seaside plantain. Plantago juncoides Lam.; P. juncoides Lam. var. decipiens (Barneoud) Fern.; P. juncoides Lam. var. glauca (Hornem.) Fern.; P. juncoides Lam. var. laurentiana Fern.; P. maritima L. ssp. borealis (Lange) Blytt & O. Dahl; P. maritima L. var.. juncoides (Lam.) Gray; P. oliganthos Roemer & J.A. Schultes; P. oliganthos Roemer & J.A. Schultes var. fallax Fern. • CT, MA, ME, NH, RI; coastal. Saline and brackish marshes, coastal cliffs and ledges, very rarely found on fresh-tidal river shore ledges. North American plants are recognized as ssp. juncoides on the basis that they are self-compatible, have broader bracts, and usually have 2- to 4-seeded capsules (European plants are usually self-incompatible, have narrower bracts, and 1- to 2-seeded capsules).
Native to North America?
Yes
