Excited to discover the most beautiful botanical gardens in California? Let’s get started!
San Francisco Botanical Garden
With more than 9,000 plants from around the world and ten themed gardens, the San Francisco Botanical Garden is a must-visit 55-acre oasis in the City by the Bay. It is one of the top Bay Area gardens to visit.
Visiting the San Francisco Botanical Garden is one of the best things to do in Golden Gate Park!
Walk through a shaded coastal redwood grove in the California garden. Elsewhere, admire fuchsias from the Andean Cloud Forest, marvel at the giant spear lilies from Australia, and take in the fragrance of herbs in the Mediterranean garden.
For a special treat, visit between December and March to see the magnificent magnolias in bloom. San Francisco Botanical Garden has the largest collection of magnolia species outside of China, and the mature trees look gorgeous when covered in white or pink blooms.
We visited in early March to see the magnolias and found many trees showing off masses of waxy blooms in dark pink, light pink, and white.
Rhododendrons, in white and shades of pink, were in peak bloom in March as well, and we also caught the tail end of the blooming of the camellias.
No matter what time of year you visit, you will find something in bloom here.

The Huntington Botanical Gardens, San Marino
The Huntington features an astounding 15,000 types of plants in 16 themed gardens, spread over 120 acres.
The complex, just outside Pasadena, makes for one of the most wonderful day trips from Los Angeles: apart from the gardens, you can also tour the Huntington Library and Art Collection when you visit.
Must-visit gardens at the Huntington include the Desert Garden, which houses one of the largest collections of succulents in the world, the Japanese Garden with its moon bridge and tea house, the Chinese Garden with its lake and architectural elements, and the Rose Garden, which has over 1,200 varieties and looks absolutely stunning in peak bloom.
A smaller garden we loved at the Huntington is the Shakespeare Garden, which contains plants and flowers from Shakespeare’s time, as well as those he referenced in his works! The herb garden nearby also makes for a lovely wander.
You’ll see something in bloom year round, but the wisteria in spring is a showstopper. Fall brings leaf color to some trees, making for lovely splashes of color.
You could see most of the gardens in one full day, if you start at opening time. On our first visit to the Huntington, we took two full days to browse the entire complex, including the art and the library.
For more information, visit the Huntington website.
Balboa Park Gardens, San Diego

Without a doubt, the best time to visit Hakone is when the cherry trees are in bloom, which generally happens at some point in March. The garden looks spectacular at that time, with clouds of pale pink blossoms everywhere you look.
That said, you can visit in other months and still enjoy the tranquility of the garden and other plants in bloom. In April, for example, wisteria and rhododendron offer lots of color.
