The Most Beautiful Botanical Gardens in the World

Whether you’re in the Northern Hemisphere or Southern, East or West, there’s always something to see at the best botanical gardens in the world. This guide covers six of the seven continents (sorry, Antarctica), including six gardens in the United States.

What are botanical gardens exactly? Merriam-Webster defines them as gardens “often with greenhouses for the culture, study, and exhibition of special plants.” The international Botanic Gardens and Plant Conservation goes a few steps further, emphasizing the purpose of scientific research and the conservation of rare and threatened plants, plus compliance with international policies and sustainability and ethical initiatives.

While the flora and fauna change from region to region—and season to season—each of these gardens offers an astonishing variety of natural and man-made wonders. These are sanctuaries of tranquility that simultaneously excite nature lovers and inspire would-be green thumbs. You don’t have to be an aspiring botanist or horticulturist to enjoy a visit; these gardens boast magnificent architecture, greenhouses, fountains, wildlife, walking tours, libraries, classes, and special events, including light shows and concerts. They’re also family friendly, less expensive than amusement parks, and good for your health—depending on how ambitious you are with your walking.

Royal Botanic Gardens, Kew

• Location: Richmond, London, England
• Hours: Daily, 10 a.m.–3 p.m. (last entry 2 p.m.)
• Tickets: $13–$30 (adults), $5–$10 (children 4–15), free for children under 4

Kew Gardens (as the gardens are better known) may be the most famous botanical park in the world and not just because it’s a UNESCO World Heritage site. It’s considered the world’s largest collection of living plants with more than 50,000 of them across 300 acres of dedicated land, including many species you’d never expect to find in England. For that, you have the climate-controlled Princess of Wales Conservatory to thank. The glasshouse (the largest Victorian one in the world) is carved into zones: One is dedicated to carnivorous plants like Venus flytraps; another to succulents and cacti; and a third is humid and tropical enough to grow Victoria amazonica, the world’s largest water lilies.

The property, founded in 1759, also has a rock garden with a tiered waterfall and an arboretum with 14,000 trees, including giant redwoods and black locusts dating to the 18th century. For the ultimate immersion, head to the edge of the garden, where a 37-acre storybook forest meets the River Thames and an elevated trail snakes through a watercolorist’s palette of wildflowers.

Singapore Botanic Gardens

• Location: Singapore
• Hours: Daily 5 a.m.–midnight
• Tickets: Free
• nparks.gov.sg/sbg

The Singapore Botanic Gardens is the only tropical botanic garden on the UNESCO World Heritage list and the first UNESCO World Heritage site in Singapore. The 203-acre green space, founded in 1859, welcomes millions of visitors a year, drawn to the lakeside gazebos, groves of wild fruit trees, the bonsai garden, three lakes, a small tropical rain forest, and a perfumed grouping of frangipani. There is also a healing garden with 400 types of medicinal plants.

Of special appeal is the 7.4-acre National Orchid Garden—the largest of its kind, with more than 1,000 wild species and 2,000 hybrids, organized into color zones.

You may see exotic animals as well; birds, frogs, lizards, bats, monkeys, pigs, turtles, otters, and other animals live here year-round. Note: Do not confuse this with Singapore’s Gardens by the Bay, a popular, man-made, and air-conditioned environment.

Montreal Botanical Garden (Jardin Botanique de Montréal)

• Location: Montreal, Canada
• Hours: Tuesday–Sunday 9 a.m.–5 p.m.
• Tickets: $23 (adults), $21 (seniors 65+), $17 (students with ID), $12 (kids 5–17)
• espacepourlavie.ca/en/botanical-garden

The stats alone are impressive: 10 greenhouses spread over 185 acres with 22,000 species of flora—and the whole garden was designated a National Historic Site of Canada in 2008. On top of all that, the Montreal Botanical Garden, created in 1936, also shows creativity in its approach. There’s a toxic plant garden and a garden of innovations that showcases new cultivars from the ornamental horticulture industry.

Depending on the season, visitors can explore an arboretum with 800 species of trees and shrubs, a Japanese garden with bonsai trees, a Chinese garden, and spaces dedicated to perennials, shade plants, ferns, succulents, roses, floating plants, medicinal plants, and, of course, flowers (especially irises, peonies, and lilies). What’s more, it maintains more than 400 species on the list of rare or threatened plants drawn up by the World Conservation Union (IUCN). And it launched the First Nations Garden in 2001, which “presents the close bonds First Nations and the Inuit have always had with the plant world.”

If you’re interested in visiting the insectarium with more than 250,000 specimens (one of the largest insect museums in North America), you need a separate ticket, which includes access to other museums, including the Biosphere and Biodome.

Jardim Botânico

• Location: Rio de Janeiro, Brazil
• Hours: Monday, Tuesday, Thursday–Sunday 8 a.m.–5 p.m.
• Tickets: $15 (cash only)
• gov.br/jbrj/en

Rio’s 350-acre Jardim Botânico was founded in 1808 by D. João VI of Portugal, prince regent (eventually king) of the United Kingdom of Brazil and Portugal. It has a reputation as one of the finest tropical gardens on Earth, bordered by the world’s largest urban forest, Tijuca National Park. Of its 7,000-plus species of tropical plants, the vast majority are native to Brazil. It also has 2,000 species of orchids. And while you may see the garden’s Avenue of Royal Palms surface repeatedly on Instagram, its rare bromeliads and traditional Japanese garden—including cherry trees and bonsai—are not to be missed.

Note to birders: Bring your binoculars because hundreds of species nest in this garden.

Arctic-Alpine Botanical Garden

• Location: Tromsø, Norway
• Hours: Open 24 hours, seven days a week
• Tickets: Free
• en.uit.no/tmu/botanisk

The Arctic-Alpine Botanical Garden, the world’s northernmost botanical garden, showcases traditional perennials and herbs from the tippy-top of Norway, plus a surprising array of plants from other continents. Part of the University of Tromsø, the garden has 25 collections in total; it specializes in Arctic and Antarctic plants (a rarity), as well as species native to the Himalayas, South America, and Africa. The garden is open year-round and free to visit, but most flowering takes place between May and October. In winter, BYO skis to experience the AABG’s evergreen shrubs and snow-capped rockscapes.

Kirstenbosch National Botanical Garden

• Tickets: $12 (adults), $2 (children 6–17)
• sanbi.org/gardens/kirstenbosch

It’s hard to beat a backdrop that includes Table Mountain National Park. Set in the eastern slopes of South Africa’s most iconic landmark, the world-renowned Kirstenbosch National Botanical Garden lives up to the hype. There are 1,305 acres with more than 7,000 species of plants, most of which are native to the Cape and southern Africa.

Located eight miles from the heart of Cape Town, and founded in 1913, the garden is blessed with postcard-worthy groupings of protea and cycads, hiking and mountain biking trails, expansive lawns for picnicking, and a 427-foot treetop walkway (informally known as “the Boomslang”) that arcs gently above the arboretum’s canopy.

Royal Botanic Garden, Sydney

• Location: Sydney, Australia
• Hours: Daily 7 a.m.–sunset
• Tickets: Free
• botanicgardens.org.au

Australia’s oldest scientific institution—and one of the earliest botanic gardens in the Southern Hemisphere—the 74-acre Royal Botanic Garden is a dazzling mix of horticultural beauty and ecological conservation. Founded in 1816 and located on Sydney Harbour, a five-minute walk from the city center, it houses a collection of more than 27,000 plants from around the world, organized into 15 themed gardens. They include an air succulent garden, a tropical garden, an Australian rain forest garden, and one of the largest green walls you’ll ever see.

Unique to this institution is the Cadi Jam Ora–First Encounters Garden, which explores the relationship between plants and people; it’s located on the site where the Cadigal (an Aboriginal cultural group) and European settlers first met in January 1788. An online map offers an overview of the Victorian-era buildings, statuary, fountains, and monuments that dot the landscape.

New York Botanical Garden

• Tickets: $35 (adults 13+), $31 (seniors 65+), $31 (students with ID), $20 (children 2–12)
• nybg.org

The Bronx’s best-known National Historic Landmark was established in 1891 by botanists Nathaniel Lord Britton and his wife, Elizabeth. Inspired by a visit to Kew Gardens in England (see above), the couple founded their own botanical paradise on the north side of Bronx Park, close to an old-growth forest (the Thain Family Forest) and the babbling Bronx River. With 250 acres of land, this picturesque green space—known as the New York Botanical Garden—is the largest city-based botanical garden in the United States. Its 50 specialty gardens feature more than a million plants and 12,000 species, including lilacs and magnolias.

Highlights of any visit include a stroll through the circa-1890 Victorian-style glasshouse Haupt Conservatory, the impressive northeastern North American native plant garden, and what is widely considered one of the world’s most sustainable rose gardens. For plant nerds, there is also the Mertz Library, the largest botanical research library in the USA and the first library whose collection focused exclusively on botany.

Missouri Botanical Garden

• Location: St. Louis, Missouri
• Hours: Daily 9 a.m.–5 p.m.
• Tickets: $14 (adults 13+)
• missouribotanicalgarden.org

Established in 1859 by merchant Henry Shaw, this National Historic Landmark is America’s oldest botanical garden still in continuous operation. Its 79-acre spread is best known for the Climatron, a geodesic-dome greenhouse with a rain forest–like climate, dense tropical foliage, and a river aquarium teeming with fish. More than 2,800 plants grow inside, including cacao and coffee.

The institution has earned international acclaim for its comprehensive botanical reference library and herbarium with more than 6.5 million mounted specimens (the second-largest in the USA). Other notable draws include the 14-acre Japanese strolling garden, one of the oldest in the nation, and an 8,000-square-foot glass butterfly conservatory housing more than 60 species of winged beauties and 100 species of exotic flowering plants.

Desert Botanical Garden

• Location: Phoenix, Arizona
• Hours: October–April daily 8 a.m.–8 p.m.
• Tickets: $30 (adults), $17 (kids 3–17)
• dbg.org

Snuggled into the dusty red rocks of the Papago Buttes Park, the 140-acre Desert Botanical Garden has more than 50,000 arid plants and 4,482 species in its unique collection. Of those, 379 species are rare and endangered.

Founded in 1939, the garden has gotten creative with its programming, offering desert landscaping classes for homeowners and five themed hiking trails that are especially nice for families. It’s not just a trove of succulents and cacti, either. There’s also a desert wildflower garden dedicated to brightly colored blooms and the pollinators they attract, like bees, butterflies, and hummingbirds.

You can get a sense of history here, too. Travel along the Sonoran Desert Nature Loop to learn how the region’s Tohono O’odham and Western Apache people used native plants.

Longwood Gardens

• Location: Kennett Square, Pennsylvania
• Hours: Wednesday–Monday 10 a.m.–5 p.m. (March 30–May 8 until 6 p.m.)
• Tickets: $30 (adults 19+), $27 (seniors 62+ and students with ID), $23 (military/veteran), $16 (kids 6–18)
• longwoodgardens.org

Longwood has a rich history, starting with the native Lenni Lenape tribe, which fished, hunted, and planted on the 1,077-acre estate for thousands of years. In 1906, wealthy entrepreneur Pierre S. du Pont bought the land and started to build his own gardens, one by one, drawing heavily on recent visits to renowned gardens in Europe.

He was especially impressed with fountains at the time; he had seen the majestic water pumps at the 1876 Centennial Exposition in Philadelphia. So Longwood, naturally, has plenty of them—hundreds. Over decades, Longwood has added a conservatory, a plant nursery, an experimental greenhouse, a desert house, 13 outdoor water lily pools, a meadow garden, tree houses, tropical plants, a plant-breeding program, and a visitor center with a shop, auditorium, and 1,000-car parking lot.

In the fall of 2024, the garden will be unveiling what it is calling “a sweeping reimagination of 17 acres of the Conservatory and grounds.”

Chicago Botanic Garden

• Location: Chicago, Illinois
• Hours: 10 a.m.–3 p.m.
• Tickets: $10–$15 (adults 13+), $10–$12 (children 3–12), children under 3 are free; the garden offers occasional free days, check its calendar
• chicagobotanic.org

Depending on the season (and which exhibits are on view), visitors at the Chicago Botanic Garden can enter a habitat filled with live butterflies, admire 26 replicas of roadside attractions in the Model Railroad exhibit, or take in the 385 acres of nature and beauty while seated on a free tram tour.

What kinds of gardens will you find? There’s a rose garden, a fruit and vegetable garden, a world-class bonsai collection, and more than 200 dwarf trees, including evergreens, maples, and magnolias. The kaleidoscope of color is spread across nine islands and six miles of lakeshore. To explore what’s in bloom when you visit, download the interactive plant-locating app and take one of the offered walking tours.

The Huntington Botanical Gardens

• Location: San Marino, California
• Hours: Wednesday–Monday 10 a.m.–5 p.m.
• Tickets: $25–$29 (adults), $21–$24 (seniors 65 and students 12–18 or full-time with ID), $13 (children 4–11), children under 4 free
• huntington.org

Located 12 miles from downtown Los Angeles, the Huntington is a fantastic, massive campus that sits on 130 acres, boasting more than 83,000 living plants. It’s impossible to see everything in one day. Some of the themed gardens are so spectacular that you could visit just for that collection. The desert garden, for example, is one of the largest outdoor collections of cacti and succulents in the world and includes more than 5,000 species of desert plants. Among the striking specimens, seek out the boojum trees (Fouquieria columnaris).

The grounds also have gardens dedicated to different types of plants (roses, herbs, palm trees) as well as nations (Australia, China, Japan), plus lily ponds and a mausoleum. You want a cool selfie in nature? You could shoot a month’s worth of content here in a day.
