White-Plumb Farm was homesteaded and the house was built by Colonel Charles A. White, one of the original founders of the Union Colony in Greeley. Originally a 160-acre tree claim, trees were planted by 1881 in order for the family to obtain the Timber Culture Patent on the land in 1892. The house at White-Plumb Farm was designed by Bessie Smith, at the time Denver’s only woman architect, and is listed on the National Register of Historic Places.
