At Sage Ranch native plants are well represented within the oak woodland of ceanothus, coffee berry and California buckwheat. Over-grown orange and avocado groves fill out the ranch's diverse flora. Springtime wild flowers color the edges of the trailside. There are bush lupine, California poppy, sunflowers, cream cups and many more. Bracken and sword fern grow in the park's lush corners.
Dry areas have prickly pear cactus.
It was once the wild, wild west. Now it rests between Los Angeles and Ventura Counties. Major freeways serve the area, like the Simi Valley Freeway on the north, the Ventura Freeway on the south, Valley Circle Boulevard and Topanga Canyon Boulevard on the East, and finally, California 23 on the West. Bordering Sage Ranch to the south is the Rocketdyne Santa Susana Field Laboratory, established in 1958. Rocket engine testing can be a noisy business, so the company chose the site, then called Paradise Valley, because of its isolation.
