Hayes Mansion and Edenvale Gardens Regional Park, San Jose, CA
This area has an interesting history. It was homesteaded by a family called Hayes in the late 1800's and has been designated as an historic landmark.
In gathering data for iNaturalist.org, I noticed that the Edenvale Garden Park associated with the Hayes Mansion appears to have 1-2 each of about a hundred different species of trees. Some of the eucalyptus trees and oaks are massive, so I'm guessing they've been there a hundred years or more. The Hayes gardens extended beyond the current boundaries of the mansion and park (now only 6 acres). I've seen Coulter's pine and redwoods in the adjacent mobile home community. Also, there were giant agaves before they cut them down for the newest construction project.
I found a book at Santa Clara Central Park Library called "The Gem of Edenvale - The Historic Hayes Mansion of San Jose, California" by Nancy L. Neulin (Renasci, 1994). She wrote that the Hayes family hired Rudolph Ulrich to design the park and gardens. Scattered throughout the park were ponderosa pine, pepper, Italian cypress, and black locust. Palm, cedar, and eucalyptus lined the paths, which were wide enough to drive a wagon or car through.
"In its park of 40 acres one may find trees, shrubs and flowers indigenous to every clime." (San Jose Evening News, July 27, 1905).
Neulin confirmed my suspicions: "The natural trees, principally pines and the beautiful California live-oak, have been left as nearly in a state of nature as possible." (pp. 64-65)
The Hayes Estate originally comprised 646 acres as of 1903. Surrounding the current historical site were hundreds of acres of orchards and fields - a large working farm that produced: prunes, apricots, peaches, pears, cherries, apples, figs, dates, oranges, lemons, grapefruit, strawberries, blackberries, gooseberries, loganberries, almonds, English walnuts, pecans, chestnuts, oats, barley, wheat, alfalfa, peas, corn, beets, lima beans, carrots, cauliflower, eggplant, potatoes, garlic,artichokes, lettuce, squash, and horseradish.
Neulin tells an interesting story about a construction worker finding a barn owl nest with two hatchlings and three eggs behind the soffit panels in the old mansion in 1993 during the renovation. The hatchlings and eggs were taken to the Humane Society, where the owls were raised, and eventually released back into the park where the construction worker had made nesting boxes for them.
