California Hillside Poppies is a studio produced painting, copied from a painting by William F. Jackson (1850 – 1936). Jackson was a California artist who also became the first curator of the Crocker Museum in Sacramento, California.

This painting, which is illustrated in Agnes Barchus 1974 book Eliza R. Barchus: The Oregon Artist, is thought to be the only painting Eliza produced in an impressionistic style, applying her paint using a pallet knife rather than brushes.
