The Blair House gardens were created during the major renovation of the house in the 1980s and were funded through generous donations from the following individuals:
- Mr. and Mrs. Jack Massey: Front gardens (facing Pennsylvania Avenue)
- Arthur and Janet Ross: Arthur and Janet Ross Garden (large interior garden, above)
- Fleur Cowles: Small interior courtyard
Mr. and Mrs. Ross subsequently endowed the gardens to maintain and preserve them in perpetuity.
