2. Sesbania tomentosa (Oahu River Hemp)

Sesbania tomentosa, also called Oahu River Hemp, is a rare flowering shrub native to Hawaii’s coastal dunes and dry lowlands. This endangered plant produces bright red, pea-shaped blossoms that add a burst of color to the landscape. Its silvery-green, velvety leaves give it a soft, attractive appearance even when not in bloom.

Traditionally, this plant held significance in Hawaiian culture, with its strong fibers once used for cordage and net-making. Ecologically, it helps stabilize sandy soils and supports native pollinators like bees and butterflies.

Historically, Native Hawaiians recognized the plant for its medicinal properties, although its milky sap can be toxic if not handled properly. Ecologically, Pua Kala supports native pollinators and contributes to the biodiversity of dry Hawaiian landscapes.

Gardening tip: Pua Kala can be grown in dry, rocky soils with full sun exposure. Be cautious when handling due to its spines.

4. Abutilon eremitopetalum

Abutilon eremitopetalum is an exceptionally rare flowering shrub found only in Hawaii, primarily on the island of Lānai. This native plant is recognized for its delicate, bell-shaped flowers, which typically appear in soft yellow or orange hues. Its foliage is velvety to the touch, adding an ornamental quality that appeals to gardeners and conservationists alike.

This species is currently endangered due to habitat loss and grazing animals, making its preservation crucial. Botanists actively propagate Abutilon eremitopetalum to protect it from extinction, and it is often found in specialized native plant gardens.

Gardening tip: If available from certified native plant nurseries, it should be grown in well-drained soil under partial sun to mimic its natural environment.

5. Geranium arboreum

Geranium arboreum, sometimes called the Hawaiian red geranium, is one of the rarest geranium species in the world, existing only in the Hawaiian Islands. Unlike the common garden geraniums, this unique plant grows as a small shrub with clusters of vibrant red flowers that stand out against its green foliage.

Its natural habitat is typically dry to mesic forests, where it plays a role in supporting local insect life. Due to habitat destruction and the introduction of invasive species, Geranium arboreum is considered endangered, and conservation efforts are ongoing to protect its limited populations.

Gardening tip: This geranium is best suited for native plant gardens and should be planted in well-draining soil with exposure to partial sunlight.

6. Hibiscus brackenridgei

Hibiscus brackenridgei, also known as the Hawaiian yellow hibiscus, is the official state flower of Hawaii. Its bright golden-yellow petals and large, showy blooms make it one of the most best Hawaiian flowers to represent the islands’ tropical beauty. This hibiscus typically blooms in spring and summer, attracting butterflies and native pollinators.

Endemic to dry forests and shrublands on several Hawaiian islands, Hibiscus brackenridgei is considered endangered in the wild due to habitat loss and grazing by non-native animals. Gardeners often cultivate it to preserve the species and enjoy its striking display in home landscapes.

Gardening tip: Plant in sunny areas with well-drained soil. Regular pruning encourages more blooms and a fuller appearance.

7. Bidens cosmoides

Bidens cosmoides, a member of the sunflower family, is one of the best Hawaiian flowers for adding height and vibrant color to gardens.

Once pollinated by now-extinct native moths, Brighamia insignis relies almost entirely on human-assisted pollination to survive. Conservation efforts have made it a symbol of Hawaii’s fragile ecosystems and the importance of protecting native species.

Gardening tip: It thrives in well-draining, sandy soil and needs bright, indirect sunlight if grown in pots. Avoid overwatering to prevent root rot.

9. Sophora chrysophylla (Māmane)

Sophora chrysophylla, commonly known as Māmane, is a native Hawaiian tree that produces clusters of bright yellow flowers, making it one of the best Hawaiian flowers for supporting local wildlife. This hardy tree thrives in dry to subalpine forests, particularly on the islands of Hawaiʻi and Maui.

The Māmane tree is ecologically significant because its flowers and seeds provide essential food for native Hawaiian birds like the endangered palila. Its golden blossoms add a cheerful burst of color to high-elevation landscapes, standing out against the rugged terrain.

11. Argyroxiphium sandwicense subsp. (Hawaiian Silversword)

Argyroxiphium sandwicense, commonly known as the Hawaiian silversword, is one of the most iconic and best Hawaiian flowers found in the high volcanic regions of Maui and Hawaiʻi. Its shimmering, silver-gray leaves form a striking rosette that reflects sunlight, protecting the plant from harsh mountain conditions. When it blooms—an event that occurs only once in its lifetime—it produces a tall stalk covered with hundreds of purple to maroon flowers.

This rare plant is highly protected, as it grows only in specific alpine environments such as Haleakalā and Mauna Kea. Its unique life cycle and spectacular bloom make it a must-see for nature enthusiasts visiting Hawaii.

Gardening tip: Hawaiian silversword is not typically grown in home gardens due to its specialized habitat needs, but it can be admired in protected national parks where it thrives naturally.

Gardening tip: ‘Ōhelo can be grown in acidic, well-draining soil in cool climates. It is perfect for native gardens or as a unique ornamental shrub in volcanic or rocky landscapes.

16. Dwarf Naupaka

Dwarf Naupaka, a compact variety of the native Naupaka shrub, is a coastal plant well-known among the best Hawaiian flowers for its unique half-shaped blooms. Each flower appears as if split in two, giving rise to the Hawaiian legend of star-crossed lovers separated between the mountains and the sea.

This hardy shrub thrives in sandy and salty environments, making it a natural choice for stabilizing dunes and protecting coastal landscapes. Its small white to pale lavender flowers attract pollinators, and its dense foliage provides shelter for native wildlife.
