Facts
Sweet-bay is a small tree (to 30 feet or 10 m tall) with light green leaves with whitish undersides. An evergreen plant further south, it hangs onto its leaves long into the fall in New England, and drops them green. It produces small numbers of showy white flowers with slightly cupped petals that give rise to aggregate fruits that split open to reveal seeds covered in red flesh (arils). Its gray bark is smooth. This species is more common in the southeast U. S., reaching the northern edge of its range in Connecticut and Massachusetts.
Habitat
Forests, swamps
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.
