The Lassen Street Olive Trees, also known as 76 Mature Olive Trees, are a Los Angeles Historic-Cultural Monument located in the Chatsworth community of the northwestern San Fernando Valley, in Los Angeles, Southern California.

History

An avenue (alleé) of Olive trees (Olea europaea) were planted in 1893 along a then dirt road by Nelson A. Gray, who owned property there. The Grays moved from Pasadena to Chatsworth in 1892. They are believed to have been grown from cuttings taken from the Spanish Colonial c. 1800 planted olive orchard trees at the Mission San Fernando Rey de España across the Valley.^[2]

When the site was designated a Historic-Cultural Monument in 1967, there were 76 olive trees along several blocks of western of Lassen Street. According to the Chatsworth Daughters of the American Revolution chapter, there are 68 trees surviving/remaining in the 2010s.^[2]
