Botanical gardens are sanctuaries where you can gaze up at a cloud-forest canopy, stick a hesitant finger inside a Venus flytrap, or contemplate a butterfly and restore your sense of awe in a civilization-weary world.
Each of these Western gardens offers distinct treasures, from fierce desert succulents to tropical fruits the size of duffel bags. What they share is a mission: to preserve a living library of plant species that exemplifies the value—and vulnerability—of the earth's flora. "People come to see pretty or unusual plants, but they walk away understanding the need for conservation," says Janet Leopold, a spokes-person for Hawaii's National Tropical Botanical Garden.
So visit one of these horticultural Edens. Your worldview and your sense of wonder will never be the same again.

Stretching from coastal prairie meadows to ferny pine forests, this oceanside paradise is famous for its tree-size rhododendrons, some of which grow nearly 20 feet tall. The exuberant blossoms abound in late spring as do heritage roses, lilies, and wildflowers, including the rare Mendocino paintbrush. Late summer and fall usher in fuchsias, hydrangeas, and dahlias. In winter the ocean-facing benches provide a great vantage point for spotting migrating gray whales.

UC-Berkeley botanists have crammed an amazing array of vegetation and habitats into the hills above San Francisco Bay. Follow a trail through a cluster of South American cacti and other arid exotica before heading into a wet world of New Zealand tree ferns and Asian lilies. Climb uphill toward a field of roses, stopping occasionally to admire the view of the Golden Gate Bridge. Nearly one-third of all native California plant species can be found on these grounds, but foreign beauties blend equally well into the landscape. The Chinese dawn redwoods make a graceful counterpoint to the five-acre grove of coast redwoods across the road.

With a Buddhist shrine perched above the Japanese Garden and Thomas Gainsborough's famous Blue Boy hanging in the nearby Erburu Gallery, the experience here is as much cultural as horticultural. Still, the living specimens hardly disappoint: 95-year-old golden barrel cacti in the Desert Garden, 200-year-old bonsai, otherworldly orchids and rare treasures in the conservatory, and in spring enough roses and magnolias to fill the air with fragrance. The popular Children's Garden includes a topiary "volcano" featuring flame red New Zealand flax and a fog grotto fueled by high-pressure nozzles—the place to get lost on a warm day.

The south shore of Kauai is home to the headquarters of the National Tropical Botanical Garden, a network of four Hawaiian gardens (plus one in Florida) that showcase the flora and history of Polynesia. McBryde Garden holds the world's largest collection of native Hawaiian plants. Con-servation is a top priority: Workers helped save the rare Brighamia through hand pollination and seed collecting. The seaside Allerton Garden, adjacent to McBryde, includes a bamboo grove and tropical fruit orchard. Limahuli Garden on Kauai's north shore features taro terraces that date back to the first wave of Polynesian immigrants. Maui's Kahanu Garden boasts 122 kinds of breadfruit trees, the largest assortment anywhere.

What would you do with 300 acres of lakefront property next to downtown Seattle? The University of Washington had a fertile idea: a botanical preserve featuring thousands of trees (including one of the largest collections of Japanese maples in the United States), willow-fringed meadows, and enough flowers to ensure color at any time of year. By spring, the crab apple and cherry blossoms can knock a person over. Bald eagles, great blue herons, ring-necked pheasant, American goldfinches, and many other birds mingle at the Union Bay Natural Area. Reclaimed more than 30 years ago from a garbage dump, this location now provides some of the best bird-watching in the city.

This mile-high landscape changes with the seasons: Lilacs and mountain flowers (such as rock jasmine from the Himalayas) burst forth in spring, water lilies abound in summer, and native leaves turn red in fall. The tropical conservatory—a domed rain forest—is a popular winter retreat. Groves of oak and cotton-wood stand tall year-round while gnarled ponderosa pines give the Japanese garden a Western ?avor.

BASICS: 1201 N. Galvin Pkwy., Phoenix, (480) 941-1225, www.dbg.org 
No surprise: This arid garden goes in huge for cacti—from ground-hugging Chilean species to a nearly 40-foot-tall cardón cactus from Baja California—as well as other sun-loving plants from around the world, including African aloes. The surrounding Sonoran Desert is especially well represented. More than 130 species in the garden are rare, threatened, or endangered. In spring, purple and yellow cactus blooms shine bright against a backdrop of red sandstone. Spring wildflowers such as desert marigolds and bluebells, along with the accompanying butterflies and rufous hummingbirds, add more splashes of color. The native butterflies in the pavilion will flutter around your head.

BASICS: 38 Tizer Lake Rd., Jefferson City, Mont., (866) 933-8789, www.tizergardens.com

The wildest of the West's gardens—black bears and moose are frequent visitors—is also the most surprising. Who imagined so many flowers, trees, and shrubs could flourish this far north? Some buds, including yellow globeflowers and primroses, open as soon as the snow melts. This is one of the few gardens where you can see the rare and brilliant Himalayan blue poppy. In June, visitors—and bears—can watch king salmon fight against the current of Campbell Creek. By the peak of summer, 22 hours of daily sunlight fuels frantic growth along the wildflower walk and the 1.1-mile nature trail through birch and spruce woodlands.

The Mesoamerican cloud forest thrives in the local fog. Other attractions include 0an authentic patch of Australian bush, a Japanese moon-viewing garden, and a collection of primitive plants such as cycads, palmlike living fossils that predate the dinosaurs. Vast lawns are perfect for picnicking, strolling, and Frisbee throwing.
ELEVATION: 2,400 feet
