Canadian populations of Anagallis minima are found in the Columbia River region of southeastern British Columbia to the South Saskatchewan River region of Alberta and Saskatchewan. The species also occurs on the southern tip of Nova Scotia. It is scattered across the Great Plains of the United States and is historically reported from Minnesota and New York, where it was last collected in 1901 and 1878, respectively.
