I live in Orange County, CA and I got to thinking that it might be nice to list plants that are native to this region. There are over a thousand plants that are native to Orange County and as I was sifting through the site I came across this one that made me crave nuts. Literally!
Juglans californica - Southern California Black Walnut
Deciduous tree that grows 8-25 feet high and 20 foot spread, takes full sun to partial shade and needs watering once a month
