Must-See Gardens in California

Stop to smell the roses—and see orchids, poppies, and weird cacti—at these horticultural hot spots

Whether you’re an amateur botanist, a backyard gardener, or even just a curious kid, you should make a beeline to California’s incredibly diverse botanic gardens. These protected oases are often peaceful retreats—and a great way to chill out on a go-go-go vacation. Some gardens are fascinating looks at individual passions, like the underground lair hand-dug by Sicilian immigrant Baldassare Forestiere, or a railroad magnate’s collection of international gardens near Los Angeles. Add one or more of our favorite green gems into your itinerary, listed here north to south, and who knows what you’ll be inspired to do—or grow—back home.

Mendocino Coast Botanical Gardens

U.C. Botanical Garden At Berkeley

Shaded by soaring (and native) coast redwoods, this 34-acre research garden and museum in the Berkeley Hills lets you follow winding paths to see naturalistic landscapes that feature more than 13,000 plant species, including rare and endangered plants.

Now overlooking the garden’s California native plant collection, the simple cottage-like building is polar opposite to Morgan’s best-known and arguably most lavish project: Hearst Castle along the Central Coast.

Bamboo Garden at the San Diego Botanic Garden

The Flower Fields at Carlsbad Ranch

Eighty-five years in the making, the Flower Fields at Carlsbad Ranch trace their beginnings to a father-and-son team of horticulturalists who dedicated themselves to the cultivation of the ranunculus flower. Whenever they spotted a notable specimen—whether because of a particularly full blossom or an out of the ordinary shade—the seed would be saved and planted the next year. Today, you can take in the stunning results of this painstaking process by simply walking the endless rows of color, or hop on a tractor-pulled wagon for a more mobile perspective. Other activities such as morning yoga, photography workshops, and wine tastings dot the Flower Fields’ calendar. Though it’s open year-round, peak season for the ranunuclus is late March through early May.
