🇼🇸 The flowers of Samoa

6 pages from Samoa: its flowers, the things made with them and the places to see them.

Samoa’s plant life thrives in a humid, tropical setting shaped by volcanic peaks and heavy rainfall. The islands are home to over 500 native flowering plants, with a third found nowhere else. Orchids are especially diverse here, making Samoa stand out among Polynesian islands for its rich orchid flora.

  • Samoa has the highest orchid diversity in Polynesia.
  • About one third of native flowering plants are endemic.
  • Over 225 fern species grow on the islands.
  • The only native gymnosperm is Cycas seemannii.
  • Conservation gardens protect rare Samoan plants.

The plant life of Samoa

The Samoan Islands, formed by volcanoes, support a wide range of plant life thanks to their tropical climate and abundant rain. Dense forests cover much of the land, from mangroves along the shore to rainforests and cloud forests higher up. The region is a hotspot for biodiversity, with hundreds of native flowering plants, ferns, mosses, and liverworts. Many plants arrived from Southeast Asia and New Guinea, but a few have roots in the Americas. Endemism is high, especially in mountain forests, and orchids are particularly numerous.

From region to region in Samoa

Plant communities shift with the landscape. Coastal areas feature mangroves and littoral scrub, while lowland rainforests once dominated the flatter ground. As elevation rises, montane rainforests and cloud forests take over, harboring many unique species. Some islands, like Savaiʻi and Upolu, have extensive high-altitude habitats supporting mosses and liverworts. The diversity of vegetation zones—from swamps to volcanic scrub—reflects the islands’ varied terrain.

Flowers to know in Samoa

Orchids are a hallmark of Samoa’s flora, with over 100 native species, more than anywhere else in Polynesia. Some, like the large purple orchid and Samoan bulbophyllum, are unique to the islands. The Rubiaceae family, which includes the noni tree (Morinda citrifolia), is also well represented. Rare and possibly extinct plants include several Cyrtandra species and endemic orchids. The only native gymnosperm is a cycad, Cycas seemannii.

How flowers are used in Samoa

Many Samoan plants are woven into daily life and tradition. Some are grown for food, others for building materials or as part of ceremonies. Traditional medicine draws on local species, though details are not specified. Conservation gardens and protected forests help preserve plants important to culture and heritage.

Threats and protection in Samoa

Much of the original lowland forest has been cleared for farming and timber. Invasive species also threaten native plants, prompting control efforts. Conservation projects focus on protecting habitats and rare species, such as the rainforest at Falealupo and the Vailima Botanical Gardens. Some plants are now extremely rare or may have disappeared entirely.
