A paradise for garden lovers, Hawaii is a dream destination with a breathtaking array of botanical wonders. The islands’ unique climate and volcanic soil create the perfect conditions for a diverse range of plant life, from lush tropical rainforests to striking dryland gardens. 

Here, rare and exotic species flourish alongside native Hawaiian plants, many of which are found nowhere else on Earth. Whether you’re drawn to vibrant orchids, fragrant plumerias, or towering fig trees, a trip to Hawaii’s gardens is a one-of-a-kind opportunity to witness nature’s artistry in full bloom. 

If you appreciate horticulture, history, and breathtaking scenery, little compares to the many beautiful gardens of Hawaii. 

Hawaii’s Unique Botanical History 

Hawaii’s breathtaking biodiversity is a direct result of its remote location and geological history. Isolated in the middle of the Pacific Ocean (approximately 4,000km from Los Angeles), the Hawaiian Islands developed a unique ecosystem where nearly 90% of native plant species are found nowhere else in the world. Over millions of years, more and more plants arrived on the islands by wind, water, and birds, converging to create a vibrant ecosystem full of life. 

Early Polynesian settlers introduced staple plants such as taro, coconut, and breadfruit, which also became integral to Hawaiian culture and agriculture. Today, Hawaii’s gardens offer a glimpse into this extraordinary natural history, showcasing both ancient native flora and exotic species that thrive in the islands’ rich volcanic soil.

Why August is the Perfect Time to Visit

The summer season in Hawaii offers warm tropical weather, lush landscapes, and a stunning display of vibrant blooms. Many of the island’s iconic plants are at their peak during this time, from fragrant plumerias to striking hibiscus. Another advantage of visiting at this time is the ability to enjoy the islands’ botanical wonders with fewer crowds than that of the highly popular winter season. 

August is also typically one of the driest months in Hawaii, making it the perfect time to join our garden tours of Hawaii. While Australia experiences the depths of winter, you can soak in the Hawaiian sun and explore the native exotic flora that makes this one of the most incredible regions on earth.

Must-See Gardens Destinations

Although Hawaii is home to a total of 137 individual islands, both Kauai and Oahu are world-famous destinations with a fantastic collection of gardens to visit. Let’s take a look at some of the best gardens on each respective island. 

Kauai

Allerton Garden

This enchanting garden on Kauai’s South Shore was once the private estate of Queen Emma and is now part of the National Tropical Botanical Garden. With its meticulously designed landscapes, hidden water features, and stately Moreton Bay fig trees made famous in countless Hollywood films, a visit to Allerton Garden is a truly unforgettable experience. 

Here, you’ll find an abundance of tropical blooms, including vibrant heliconias, gingers, and bromeliads, all set against the backdrop of the garden’s sculpted terraces and shaded walking paths. Visitors can also discover the unique breadfruit collection, which plays a significant role in Hawaiian culture.

Limahuli Garden & Preserve 

Nestled in a verdant valley on Kauai’s North Shore, Limahuli Garden is a breathtaking example of how both native and introduced plants can thrive together in harmony. At the Limahuli Garden, you can witness the thriving taro fields, canoe plants such as banana and breadfruit, and a striking array of tropical flowers, including bright red ‘ōhi‘a lehua blossoms and native hibiscus. 

The garden also offers sweeping views of the Pacific Ocean that make it one of the most picturesque locations on the island.

Waimea Canyon

While not as much of a “traditional” garden, Waimea Canyon’s stunning landscapes make it another must-see. Known as the “Grand Canyon of the Pacific,” this awe-inspiring natural wonder is filled with vibrant greenery and seasonal wildflowers that come to life during the warmer months. 

Hiking trails wind through the canyon, offering breathtaking panoramic views, cascading waterfalls, and diverse native vegetation such as koa and sandalwood trees. At higher elevations, cooler temperatures make for a comfortable and rewarding outdoor adventure, perfect for nature lovers and photography enthusiasts alike.

Oahu

Foster Botanical Garden 

Located in the heart of Honolulu, Foster Botanical Garden is a living museum showcasing a remarkable collection of tropical plants. Spanning 14 acres, this historic garden is home to towering rainforest trees, rare orchids, and some of the oldest and most significant botanical specimens in Hawaii. 

Summer is an ideal time to admire the intoxicating fragrance of flowering cannonball trees, the vibrant blooms of the orchid collection, and the striking colours of the garden’s diverse palms and cycads. Visitors can also explore the Butterfly Garden, where native Hawaiian butterflies flutter among nectar-rich flowers, creating a magical experience.

Lili‘uokalani Botanical Garden

Once the personal retreat of Queen Lili‘uokalani, this peaceful garden is devoted to native Hawaiian plants, offering a rare glimpse into the natural flora that thrived before foreign species were introduced. 

Summer visitors can enjoy the serene atmosphere, shaded pathways, and views of Waikahalulu Waterfall, surrounded by vibrant flora such as native hibiscus, ‘ōhi‘a lehua, and fragrant white naupaka. This garden is a true sanctuary, with a tranquil ambience that provides a perfect escape from the bustling city while celebrating the botanical heritage of the land.

Koko Crater Botanical Garden

Situated within the dramatic landscape of Koko Crater, this unique 60-acre garden features dryland plants that thrive in Hawaii’s arid climate. Unlike the lush rainforests found elsewhere, Koko Crater Botanical Garden highlights the beauty of drought-resistant species, including towering cacti, unusual succulents, and vibrant aloes.

Due to these ecological conditions, the summer months are the perfect time to see the plumeria grove in full bloom, with its striking pink, yellow, and white blossoms perfuming the air. Walking through the garden’s loop trail, visitors will encounter rare and endangered Hawaiian species, as well as plants from Africa, Madagascar, and the Americas that thrive in similar conditions.

Additional Highlights

Manoa Heritage Centre

Situated in the lush Manoa Valley on Oahu, this garden is dedicated to preserving native and indigenous plant species, many of which have deep ties to Hawaiian history and culture. As you explore the garden, you’ll discover plants that were introduced by the first Polynesian settlers, including vital crops like taro, sweet potato, turmeric, and coconut, all of which played essential roles in Hawaiian life.

At Manoa Heritage Centre, you’ll also learn about the cultural significance of these plants, some of which are now endangered, and how they were used for food, medicine, dyes, and tools. This garden not only preserves rare species but also fosters an understanding of their beneficial properties and the traditional knowledge passed down through generations. 

Queen’s Emma Summer Palace: A Royal Garden Escape

Step back into the 19th century with a visit to Queen Emma’s Summer Palace, an idyllic retreat once owned by Queen Emma, the wife of King Kamehameha IV. Nestled in the cool, green slopes of Punchbowl Crater in Honolulu, this Hawaiian-Victorian palace provides a glimpse into royal life during Hawaii’s monarchy. Now managed by the Daughters of Hawaii, the palace is a historic site that showcases the queen’s personal belongings and the stories of her reign.

Beyond the charming architecture, the palace’s garden is equally remarkable, offering a tranquil setting filled with tropical plants, including fragrant plumerias, hibiscus, and native ferns. This peaceful retreat provides the perfect place to reflect on Hawaii’s royal history while enjoying the beauty of its lush gardens.
