From the Guidebook:
Pellier, native of Saint-Hippolyte,
France and founder of California's prune industry, came
to California in 1849. In October 1850 he established
a nursery called City Gardens. Here, aided by his brothers
Pierre and Jean, who came over from France at a later
date, he introduced the French prune-la petite prune d'Agen-into
California during the winter of 1856-57.
