A Florist Guide to Flowers Grown in Pacific Islands

Overview of Pacific Island Floriculture

The Pacific Ocean, covering nearly one-third of Earth’s surface, contains thousands of islands ranging from high volcanic peaks to low coral atolls, from large landmasses like New Guinea to tiny uninhabited islets. This vast geographic expanse creates extraordinary floral diversity shaped by isolation, colonization patterns, volcanic soils, coral limestone substrates, trade winds, cyclones, and human introduction of species over millennia of seafaring cultures. Pacific island flowers range from ancient Gondwanan relicts to recent colonizers, from endemic species found nowhere else to pan-tropical species spanning the ocean, from rainforest orchids to salt-tolerant coastal pioneers.

The Pacific islands are traditionally divided into three cultural-geographic regions: Melanesia (meaning “black islands,” including New Guinea, Solomon Islands, Vanuatu, New Caledonia, Fiji), Micronesia (meaning “small islands,” including Palau, Guam, Marshall Islands, Kiribati, Nauru), and Polynesia (meaning “many islands,” including Hawaii, New Zealand, Samoa, Tonga, Tahiti, Easter Island, and the vast triangle they define). Each region exhibits distinct floristic patterns based on geology, isolation, and human history.

Melanesia

Papua New Guinea

Papua New Guinea, occupying the eastern half of New Guinea plus numerous islands, contains some of Earth’s most biodiverse and florally rich ecosystems. The island’s position on the Australian tectonic plate, its ancient Gondwanan connections, and its dramatic topography from coastal swamps to 4,000+ meter mountains create exceptional habitat diversity.

The Queen of Sheba orchid or other orchids are nationally significant, though no single national flower is officially designated. Papua New Guinea contains over 2,500 orchid species, representing one of the world’s greatest orchid diversities. The Dendrobium genus is exceptionally diverse with hundreds of species. Bulbophyllum orchids include bizarre species with strange shapes and odors. The extraordinary Dendrobium cuthbertsonii blooms in vibrant reds, purples, yellows, and oranges at high altitudes. Paphiopedilum slipper orchids occur in limited areas. Tree-dwelling epiphytic orchids dominate rainforest canopies while terrestrial species grow in grasslands and montane forests.

Rhododendrons are spectacularly diverse with over 160 native species, more than any other region outside the Himalayan-Chinese arc. These range from sea level to alpine zones, with flowers in white, pink, red, orange, and yellow. Rhododendron macgregoriae blooms brilliant scarlet at high altitudes. Rhododendron zoelleri produces orange flowers. Some species grow as epiphytes on trees. The highlands bloom with rhododendrons creating spectacular displays.

Polynesia

Hawaii

Hawaii’s isolated volcanic archipelago evolved extraordinary endemic flora through millions of years of isolation. Over 90% of native plants are endemic, found nowhere else.

The yellow hibiscus (Hibiscus brackenridgei, called ma’o hau hele in Hawaiian) is the state flower, endemic to Hawaii and blooming bright yellow. This declaration replaced the red Hibiscus rosa-sinensis (introduced) in 1988 to honor native flora. Individual islands have specific flowers:

Oahu: the ‘ilima (Sida fallax) produces small yellow-orange flowers used in lei, requiring hundreds of delicate flowers per lei. Maui: the lokelani (pink cottage rose, Rosa damascena), introduced but beloved. Hawaii (Big Island): the ‘ohia lehua (Metrosideros polymorpha) produces brilliant red bottlebrush flowers (occasionally yellow, orange, or salmon), sacred to Pele and ecologically dominant across lava landscapes. Kauai: the mokihana (Peucedanum sandwicense) produces small flowers but is known for aromatic berries used in lei. Molokai: the white kukui (candlenut, Aleurites moluccanus) produces white flowers before oily nuts. Lanai: the kaunaoa (yellow-orange dodder, Cuscuta sandwichensis) is a parasitic vine with tiny flowers. Niihau: the pupu shell isn’t a flower but the island celebrates shells; vegetation is similar to Kauai. Kahoolawe: the hinahina (Heliotropium anomalum, native heliotrope) produces white flowers and survived the island’s use as a bombing range.

Endemic Hawaiian flowers demonstrate extraordinary adaptive radiation:

The Hawaiian lobeliads (bellflower family) evolved into over 125 species from a single ancestor, displaying incredible diversity in flower shapes, colors (white, yellow, pink, red, purple), and sizes. Many evolved curved flowers matching the bills of specific Hawaiian honeycreeper birds (now mostly extinct). The tree lobelia Cyanea species produce dramatically curved flowers. The Clermontia species bloom tubular flowers. Many are critically endangered.

Hibiscadelphus (endemic hibiscus relatives) include species like H. giffardianus with curved yellow-orange flowers that evolved for bird pollination. Several species are extinct or critically endangered.

Hibiscus native species include about 7 endemic species beyond the state flower. Hibiscus arnottianus (endemic) produces white flowers with curved styles, evolved for bird pollination. Hibiscus clayi blooms red-orange. The introduced Hibiscus rosa-sinensis hybridizes extensively, creating thousands of Hawaii-bred varieties in every imaginable color and form.

Plumeria (frangipani, locally melia), though introduced from Central America, became culturally paramount in Hawaii. Countless varieties and hybrids bloom in every color except blue: white, yellow, pink, red, orange, and multicolored. Hawaiian lei culture extensively uses plumeria. The University of Hawaii and private breeders developed unique Hawaiian varieties.

Orchids are mostly introduced but Hawaii became a major orchid breeding and production center. Dendrobium, Vanda, Oncidium, Cattleya, and other genera are cultivated extensively. The University of Hawaii developed numerous hybrids. Vanilla orchids are grown for vanilla beans.

Bird of paradise (Strelitzia reginae), introduced, thrives and became associated with Hawaiian tropical aesthetic. Heliconias, introduced from Latin America, grow prolifically with dozens of species cultivated. Gingers including white ginger (Hedychium coronarium), yellow ginger (H. flavescens), red ginger (Alpinia purpurata), pink ginger, and torch ginger (Etlingera elatior) bloom spectacularly. White ginger became naturalized and is used extensively in lei despite being introduced.

Anthuriums, introduced from South America, became a major Hawaiian agricultural product. The University of Hawaii and local breeders developed hundreds of varieties in red, pink, orange, white, lavender, green, and novelty colors. Hawaii supplies anthuriums globally.

Native Ohia lehua (Metrosideros polymorpha) dominates Hawaiian forests from sea level to treeline, blooming red (most common), yellow, orange, or salmon bottlebrush flowers. Hawaiian legend says picking the flowers causes rain. The tree is sacred to Pele, the volcano goddess. Rapid Ohia Death disease threatens this keystone species.

Koa (Acacia koa), Hawaii’s native acacia, produces cream-colored ball flowers and is culturally sacred, providing wood for canoes and ukuleles. Naupaka comes in two forms: naupaka kahakai (Scaevola taccada) grows on beaches with half-flowers (white), and naupaka kuahiwi (S. gaudichaudiana) grows in mountains, also with half-flowers. Legend says lovers torn apart, with one flower on the beach and one on the mountain.

Pua kala (Argemone glauca, Hawaiian prickly poppy) blooms white flowers and is endemic, considered sacred in traditional Hawaiian medicine and ceremony. Ilima (Sida fallax) produces delicate yellow-orange flowers requiring hundreds to make a single lei. This endemic plant holds royal significance; lei made from it were reserved for ali’i (royalty).

Koki’o encompasses several endemic Hawaiian hibiscus species: Kokia kookeri (red flowers, extinct in wild but cultivated), K. drynarioides (red-orange), and others. These rare endemics demonstrate Hawaiian evolutionary distinctiveness. Wiliwili (Erythrina sandwicensis) blooms orange, yellow, salmon, or greenish flowers and is endemic, providing lightweight wood traditionally used for outrigger floats.

Naio papa (Myoporum sandwicense) produces small white flowers. Mamaki (Pipturus albidus) produces tiny flowers but is important for traditional Hawaiian tea. Maile (Alyxia stellata) produces small fragrant flowers but is sacred for its aromatic leaves used in open lei for special occasions. Palapalai (fern, spore-producing) is sacred but non-flowering.

Introduced species dominate lowland Hawaii: Bougainvillea cascades everywhere in shocking colors. Ixora (“Maui sunset” and other varieties) bloom continuously. Alamanda vines produce yellow trumpets. Gardenia blooms fragrant white. Jasmine varieties perfume gardens. Pikake (Arabian jasmine, Jasminum sambac) is beloved in Hawaiian culture, named after the peacock (pikake) by Princess Ka’iulani.

Crown flower (Calotropis gigantea) blooms white or purple and is used extensively in lei, particularly for funerals. Roses thrive at elevation. Proteas from South Africa grow commercially on Maui and Big Island. Pincushions (Leucospermum) are cultivated. Hydrangeas bloom at elevation. Jacaranda blooms purple on Maui and Oahu.

Passionflowers (Passiflora species) climb prolifically, with some naturalized species creating problems. Thunbergia vines bloom. Bougainvillea varieties are extensively hybridized. Shower trees (Cassia species) bloom in rainbow colors: golden shower (yellow), pink shower, rainbow shower (pink-red-yellow combinations). These line streets creating spectacular displays. African tulip tree blooms orange-red. Flamboyant tree (Delonix regia) creates red displays.

Tiare (Tahitian gardenia, Gardenia taitensis), though Tahitian, is cultivated in Hawaii and used in lei. Tuberose produces intensely fragrant white flowers used in lei. Puakenikeni (ten-cent flower, Fagraea berteriana) blooms white turning orange with intense fragrance, used in lei. Stephanotis (Madagascar jasmine) produces waxy white fragrant flowers for lei and bridal bouquets.

Hawaiian lei culture represents one of the world’s most sophisticated flower traditions. Different flowers, colors, and styles carry meaning: maile for respect and honor (open lei), pikake for romance, ilima for royalty, plumeria for joy, ginger for vibrance, orchids for luxury, kukui nut for enlightenment. Lei protocol is culturally significant: never refuse a lei, drape over shoulders (don’t remove over head until later), pregnant women shouldn’t wear closed lei.

Hawaii’s horticulture industry produces orchids, anthuriums, tropical foliage, and flowers for global export. The climate allows year-round production. Challenges include Rapid Ohia Death, invasive species (miconia, strawberry guava, fountain grass), climate change impacts, and loss of pollinators (many native birds extinct). Conservation efforts focus on preserving the extraordinary 90% endemic flora through seed banking, cultivation, and habitat protection. Many endemic species survive only in cultivation or tiny wild populations.

French Polynesia (Tahiti and Islands)

French Polynesia’s 118 islands spanning five archipelagos (Society, Tuamotu, Gambier, Marquesas, Austral) create diverse floristic zones with strong Polynesian cultural connections to flowers.

The Tiare Tahiti (Gardenia taitensis) is the national flower and cultural symbol of French Polynesia, blooming pure white with intense fragrance, single or double petals. Every Tahitian knows its perfume. Women wear tiare flowers behind the ear (right if single, left if married), in hair crowns, leis, and for scenting coconut oil. The flower opens white and turns cream, remaining fragrant for days. It’s used in traditional mono’i oil (tiare macerated in coconut oil) for skincare and hair. Cultivation is widespread with gardens, roadsides, and yards featuring tiare bushes.

Hibiscus varieties bloom prolifically. The aute (Hibiscus rosa-sinensis) blooms in every color. Traditional Polynesians wore large red hibiscus flowers. The purau (Hibiscus tiliaceus, beach hibiscus) produces yellow flowers turning orange and provides fiber for tapa cloth. Plumeria (Pua) perfumes islands in white, yellow, pink, and multicolored varieties, used extensively in lei (hei) and hair decorations.

Orchids thrive with numerous cultivated species. Vanilla (Vanilla tahitensis) orchids are economically crucial, producing aromatic vanilla beans distinct from Mexican vanilla, with floral, fruity notes. Tahitian vanilla is hand-pollinated, creating expensive premium vanilla. The orchids climb trees producing cream-colored flowers. Tahiti and Taha’a are vanilla centers.

Frangipani varieties perfume everywhere. Bougainvillea cascades in shocking colors. Ixora blooms continuously. Alamanda produces yellow trumpets. Bird of paradise grows in gardens. Heliconias bloom dramatically in reds, oranges, and yellows. Gingers including torch ginger create displays. Anthuriums thrive in humidity.

The tamanu (Calophyllum inophyllum) produces white flowers before nuts yielding valuable oil. Tiare Apetahi (Apetahia raiateensis), endemic to Raiatea’s Mount Temehani, blooms unique white flowers opening in the early morning with a distinctive sound, sacred in Polynesian legend. This highly endangered endemic has five petals arranged distinctively.

Pitate (Barringtonia asiatica) blooms large white-pink flowers with numerous stamens, opening at night and falling by morning. Nono (noni, Morinda citrifolia) produces small white flowers before the medicinal fruit. Ylang-ylang blooms intensely fragrant yellow flowers. The pua (generic term for flower) concept is central to Tahitian identity.

Moorea and Bora Bora feature resort landscaping with elaborate tropical flowers. The Marquesas Islands have unique flora with endemic species. Hau (Hibiscus tiliaceus) is important. The Tuamotu atolls have limited flora due to coral limestone: coconut palms, screw pines, purau, and salt-tolerant species dominate. The Gambier Islands feature volcanic soil supporting diverse flowers. The Austral Islands’ cooler subtropical climate allows different species.

Black pearl cultivation intersects with flower culture; women wear flowers with pearls. The heiva festival features elaborate flower costumes. Pitate, rea, and native flowers are culturally significant. Gardenia lei making is an art form with techniques for stringing, braiding, and crown-making passed through generations.

Samoa

Samoa’s volcanic islands feature lush tropical vegetation with strong Polynesian traditions.

The teuila (red ginger, Alpinia purpurata) is the national flower, blooming brilliant red (sometimes pink or white varieties) in dramatic spikes. The teuila symbolizes Samoan beauty, strength, and culture. It blooms year-round and is used extensively in decorations, though not traditionally in lei like softer flowers. The Teuila Festival celebrates Samoan culture with flower displays.

Hibiscus blooms everywhere with Hibiscus rosa-sinensis in every color. The *fua (flower) concept is central to Samoan culture. Women traditionally wear large hibiscus flowers behind the ear.

Niue’s self-governing status in free association with New Zealand and small population (1,600) mean limited commercial floriculture but maintaining traditional uses. Conservation focuses on endemic species in the makatea environment.

Tokelau

Tokelau’s three coral atolls (Atafu, Nukunonu, Fakaofo) represent typical low atoll floriculture challenges.

Coconut palms dominate and are culturally/economically paramount, producing flower spikes. Screw pines (Pandanus) bloom fragrant flowers and provide food and weaving materials. Breadfruit produces flowers before fruit. Plumeria is cultivated despite challenging conditions. Hibiscus survives with care.

Beach morning glory blooms purple-pink on shores. Beach naupaka produces half-flowers. Coral creeper blooms pink. Messerschmidia blooms white. Atoll flora is limited by nutrient-poor coral soils, salt spray, limited freshwater, and cyclone exposure. Traditional Tokelauan culture uses available flowers in ceremonies and decorations.

The atolls’ low elevation (maximum 5 meters) makes them exceptionally vulnerable to climate change and sea-level rise. The population is small (approximately 1,500) with many emigrating to New Zealand. Tokelau remains a New Zealand territory. The limited land area concentrates on subsistence crops with flowers as secondary. Purau grows if conditions allow.

British governance and Seventh-day Adventist faith influence the community. Flowers are used in church services and decorations. The isolation creates unique cultivated varieties from original Tahitian and British introduced species. Lantana blooms and is invasive. Conservation focuses on preserving Henderson’s pristine ecosystem from rat threats (successfully eradicated).

Easter Island (Rapa Nui)

Easter Island’s (Rapa Nui, Chilean territory) extreme isolation, deforestation history, and Polynesian-Chilean culture create unique floriculture.

The toromiro (Sophora toromiro), endemic small tree producing yellow pea-family flowers, is extinct in the wild but survives in cultivation. It symbolizes Rapa Nui’s environmental tragedy from deforestation. Efforts continue to reintroduce it. Hibiscus blooms throughout. Plumeria perfumes despite harsh conditions. Bougainvillea adds color.

The island was originally forested, but Polynesian colonizers cleared forests completely by the 1600s, causing ecological collapse. Modern vegetation is largely introduced. Eucalyptus plantations provide wind breaks. Monterey cypress grows. Agapanthus blooms blue-purple. Roses thrive. Geraniums grow.

Bananas produce flowers. Sweet potato (kumara) flowers are tiny but the crop sustained Rapa Nui after deforestation. Taro produces flowers. The makoi berry produces small flowers. Indigenous flora is largely gone. The hauhau (Triumfetta semitriloba) produces small yellow flowers and may be indigenous.

The moai statues stand among grasslands now, but pollen analysis shows original palm forests. Chilean governance since 1888 influenced introduced species. Rapa Nui culture maintains Polynesian identity despite isolation and tragedy. The Tapati Rapa Nui festival features flower decorations. Lantana is invasive. Conservation focuses on reintroducing endemics and controlling invasives in Rapa Nui National Park (UNESCO World Heritage).

New Zealand (Aotearoa)

New Zealand’s isolation for 80+ million years created unique Gondwanan flora with extraordinary endemism (approximately 80% of vascular plants endemic). Technically temperate rather than tropical Pacific, but included for regional completeness.

The kowhai (Sophora species, particularly S. microphylla) produces brilliant yellow pea-family flowers in spring, though not officially national. The silver fern (fern, spore-producing) appears on emblems. Individual flowers hold significance: the pohutukawa (Metrosideros excelsa) blooms brilliant red in December, called the “New Zealand Christmas tree.” The rata (Metrosideros robusta and others) blooms red. The kowhai symbolizes spring.

Flax (Phormium tenax) produces red tubular flowers on tall spikes, pollinated by native birds. Culturally paramount to Māori for weaving. Cabbage trees (Cordyline species) produce fragrant cream flower panicles. Manuka (Leptospermum scoparium) produces white-pink flowers, creating famous manuka honey. Kanuka (Kunzea species) blooms similar white flowers.

Harakeke (flax) blooms dramatically. The koromiko (Hebe species) produces white-purple flower spikes; New Zealand contains most of the world’s Hebe diversity. Clematis (Clematis species) climbs with white flowers. Kowhai ngutukaka (Clianthus, kakabeak) blooms distinctive red claw-shaped flowers, endangered. The Mount Cook lily (Ranunculus lyallii, actually a giant buttercup) blooms white in alpine areas.

Celmisia (mountain daisies) bloom white across alpine zones in dozens of endemic species. Gentians (Gentiana species) bloom blue-white. Forget-me-nots (Myosotis species) include endemic alpine species. Hebes are exceptionally diverse with hundreds of species, mostly endemic. Edelweiss (Leucogenes species, New Zealand edelweiss) blooms white in mountains.

Kowhai blooms signal spring nationwide. Rata and pohutukawa blooming signals Christmas/summer. The puawhananga (clematis) climbs with masses of white flowers. Renga renga lily (Arthropodium cirratum) blooms white. The NZ iris (Libertia species) blooms white.

Introduced species dominate lowland gardens: roses, hydrangeas, rhododendrons, azaleas, camellias, magnolias, daphnes, and countless northern hemisphere species thrive in the temperate climate. Gorse (European, invasive) blooms yellow. Scotch broom (invasive) blooms yellow. Lupines (naturalized from North America) create spectacular displays but threaten natives.

Māori traditional culture uses flowers in ceremonies, particularly kowhai and pohutukawa. The karaka tree produces flowers before toxic berries (detoxified for food). The titoki produces flowers. Nikau palm (New Zealand’s only native palm) produces flowers. The puarangi produces flowers.

New Zealand’s geographic span from subtropical north to sub-Antarctic south creates diverse flowering zones. The sub-Antarctic islands (Auckland, Campbell, Antipodes, Snares) were covered in the Polar guide but represent New Zealand’s southern floristic extensions with megaherbs and unique species. Conservation challenges include invasive species, habitat loss, and decline of native bird pollinators. The kakapo, kaka, tui, bellbird, and other native birds evolved with flowers, and their decline impacts pollination.

Pacific Island Floriculture Patterns

Isolation and Endemism: Remote islands evolved unique species through isolation, creating high endemism in Hawaii, New Zealand, New Caledonia, and New Guinea. Long-distance colonization created interesting biogeographic patterns.

Human Introduction: Polynesian voyagers transported essential plants including coconuts, breadfruit, taro, yams, bananas, hibiscus, ti plants, and others, creating anthropogenic distribution patterns. European, American, and Asian contact introduced countless species.

Atoll Limitations: Coral atolls’ nutrient-poor soils, salt spray, limited freshwater, and low elevation severely constrain floriculture, creating dependence on hardy species like coconuts, screw pines, breadfruit, and salt-tolerant pioneers.

Volcanic Soil Richness: High volcanic islands’ fertile soils and elevation gradients support diverse flora from coastal to montane zones, creating exceptional diversity.

Cultural Significance: Pacific island cultures developed sophisticated flower traditions including lei/garland making, hair decorations, ceremonies, navigation markers, and spiritual connections, reflecting flowers’ cultural centrality.

Climate Change Vulnerability: Sea-level rise threatens low atolls existentially, while changing rainfall, temperatures, and cyclone intensity impact all islands. Many Pacific nations face existential climate threats.

Invasive Species: Introduced species threaten native flora globally, but islands are particularly vulnerable. Rats, mongoose, pigs, goats, invasive plants, and diseases threaten unique island ecosystems.

Conservation Challenges: Limited land area, small populations, economic constraints, and development pressures challenge conservation. However, many Pacific islands maintain strong traditional conservation ethics.
