Limahuli Garden Plant Collections

Plant collections at Limahuli Garden showcase our conservation efforts by focusing on the beauty of plants that are native to Hawaiʻi and/or culturally significant to Hawaiians. They include endemic Hawaiian species, plants introduced by the early Polynesian voyagers, as well as culturally important plants that were introduced during the plantation era starting in the mid-1800s. The collections in Limahuli Garden are used for the purposes of conservation, cultural perpetuation, and education.

Limahuli’s native plant collections focus on species from northwestern Kauaʻi. These include rare and endangered species that are on the verge of extinction in the wild such as Pritchardia napaliensis, or loulu, a native fan palm in the Arecaceae, or Palm family, found only in Limahuli Valley; Brighamia insignis, or ʻālula, a member of the Campanulaceae, or Bell Flower family, which grew only on the sea cliffs of Kauaʻi and Niʻihau; Munroidendron racemosum, a member of the Araliaceae, or Ginseng family, that is so rare that its Hawaiian name has been lost to time; and Hibiscus waimeae subsp. hannerae, or kokiʻo keʻokeʻo, a member of the Malvaceae, or Mallow family, which was once thought extinct until it was rediscovered in the back of Limahuli Valley.

Our Hawaiian ethnobotanical collection is made up of the rare varieties of crop plants that were cultivated by the early Hawaiians. These include various cultivars of taro (kalo or Colocasia esculenta),a member of the Araceae, or Arum family, which are planted in carefully restored terraces, or loʻi, once used by the ancient Hawaiians; sweet potato, or ʻuala, Ipomoea batatas, a member of the Convolvulaceae, or Morning Glory family; bananas, or maiʻa , Musa spp. in the Musaceae, or Banana family; kō, or sugar cane (Saccharum officinarum), a member of the Poaceae, or Grass family; and more. This collection also includes other early Polynesian introductions that were important components of daily life in pre-contact Hawaiʻi such as food, clothing, and medicine.

Plantation era plants include colorful and fragrant flowers, as well as tropical fruits that have become iconic symbols for Hawaiʻi. Perhaps no flower is as emblematic of Hawaiʻi as the plumeria, or melia or frangipani. Also called the lei flower, Plumeria species are tropical American members of the Apocynaceae, or Dogbane family. Other tropical flowers include many varieties of ʻawapuhi, members of the Ginger, or Zingiberaceae family, and Heliconias, in the Heliconiaceae family. Of particular significance to Limahuli are the lilia palaʻai, or daylilies, Hemerocallis sp., in the Hemerocallidaceae family, originally planted in the Valley by Juliet Rice Wichman. Of course, there are manakō, or mangoes, Mangifera indica, in the Anacardiaceae, or Sumac family, and papayas, Carica papaya, in the Caricaceae (Papaya) family.
