5 Of The Most Beautiful Botanical Gardens In The US, According To Visitors

Botanical gardens are living museums that showcase stunningly curated collections of rare plants, highlighting diversity, beauty, and ecological importance. These spaces invite visitors to explore new and exotic species, witness seasonal transformations, and be in awe of the landscaped artistry matched by few places.

The United States boasts a rich history of public botanical spaces, and the country's oldest continuously operating public botanical garden is the United States Botanic Garden in Washington D.C. It originated back in 1820, near the National Mall. The adoration of these gardens has spread, and now immaculate gardens can be found across the country. Five of the most beautiful in the United States are Longwood Gardens in Pennsylvania, the Missouri Botanical Garden in St. Louis, Coastal Maine Botanical Gardens in Maine, the Desert Botanical Garden in Phoenix, and Frederik Meijer Gardens & Sculpture Park in Michigan. 

To craft this list of the most beautiful botanical gardens in the U.S., we examined visitor feedback from review platforms, online discussion boards, and travel rankings, searching for the gardens most beloved by visitors. Let's take a closer look.

Found in Kennett Square, Pennsylvania, in the scenic Brandywine Creek Valley is Longwood Gardens, known as the best botanical garden in America. These gardens span nearly 200 acres and are meticulously crafted and curated. Originally founded by Pierre S. du Pont in the early 20th century, they have grown into a premier horticultural showcase. 

The grounds feature formal gardens, large meadows, wooded trails, and unique water features. Highlights include the historic Main Conservatory with its Neo-classical architecture and constantly rotating indoor displays. The grounds also feature a dramatic 50-foot waterfall, various rose collections, topiary gardens with their geometric designs, and the iconic Main Fountain Garden, where synchronized fountains dazzle onlookers. This theatrical blend of nature and aqua-engineering  elevate these gardens to the top.

Visitors speak glowingly of Longwood, with high marks on both Google and Tripadvisor from thousands of reviews. Tripadvisor user Sissy F. noted, "Everyone raves about Longwood Gardens, and it is absolutely worthy [of] all the praise. Plan your visit to include the evening dancing fountains. We were most impressed by the thoughtfulness and considerateness of the staff." Meanwhile, Suzanne Garber shared, "even though it was raining the evening of our visit, every detail, ornament, and bedazzled jewel were sparkling. The attention to detail and creativity put into the theme is staggering." This beautiful garden and it's fountains deserve your attention.

Found in downtown St. Louis, Missouri, the Missouri Botanical Garden occupies 79 acres and offers a reprieve from city life. It is a designated National Historic Landmark, and is one of the country's oldest and most beautiful gardens. Operating hours run from Tuesday through Sunday from 9 a.m. to 4 p.m., closed on Mondays.

This garden was established in the 19th century and continues to function as both a serene urban escape as well as a hub for research, education, and conservation. Its landscapes are diverse, including a renowned 14-acre Japanese Garden with koi ponds and a teahouse. Other areas include an English woodland, Chinese garden, and Victorian district. The Climatron greenhouse is a stunning geodesic dome and conservatory that houses tropical rainforests with waterfalls and exotic plants.

Outside of Boothbay, Maine, about an hour by car north from Portland, is the Coastal Maine Botanical Gardens. They span more than 300 acres along the rugged MidCoast shore. This garden is relatively young, having opened in 2007. It has since blossomed into a favorite among garden lovers. The gardens are open May to mid-October and welcome visitors daily from 9 a.m. to 5 p.m., rain or shine. 

The grounds are designed as a "people's garden," integrating ecology with cultivated beauty and natural landscapes. Gentle paths wind through perennial flower beds, a calming meditation garden, a children's area chock full of whimsy, a native butterfly house, and more. There's even a fairy house village with tiny creative structures all built from natural materials. A standout feature is the collection of giant trolls hidden in the forest, which were created by artist Thomas Dambo entirely out of recycled materials. These trolls, known as the "Guardians of the Seeds," hide along the wooded trails and share tales about the interconnectedness of the forest.

Visitors adore the magical atmosphere here. Visitor Lisa Whalen shared on Google: "If ever there was a truly magical place, it's here! Stunning gardens with something for everyone ... I FELT like a kid again wandering through it." Meanwhile, Chris Roybal noted: "We had a fantastic morning exploring ... Thomas Dambo's trolls drew us in, and what a perfect setting for them! As we wandered ... we were treated to spectacular views of flowers, turtles, butterflies, bees, frogs, and an abundance of other plants and wildlife." Go for the trolls, stay for the flowers.

Phoenix, Arizona, isn't exactly what you think of when a botanical garden is brought up, but the Desert Botanical Garden is sure to delight. Located in Papago Park, this garden stretches to about 140 acres and is entirely dedicated to arid-adapted flora. The botanical garden is around a 20 minute drive from downtown Phoenix.
