Facts
Common globe-amaranth is native to Asia and commonly grown as a garden ornamental. Numerous cultivars exist, with a broad range of flower colors. It occasionally escapes from cultivation in North America, and has been collected in Massachusetts. This plant is used in traditional medicine, and is known to have antihypertensive properties.
Habitat
Anthropogenic (man-made or disturbed habitats)
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.
