Lo`ulu Hiwa (Pritchardia martii)

Loulu or Loulu hiwa Arecaceae Endemic to the Hawaiian Islands Oʻahu (Cultivated) Loulu, pronounced low-loo, means "umbrella," because the leaves were formerly used as protection from rain or sun. The fruits, called hāwane or wāhane, were peeled and eaten by early Hawaiians. They collected young fruits. The flavor of young fruit with the soft interior is similar to coconut. The trunks loulu were notched for climbing to gather the immature fruits and fronds. Older specimens still bear notches that can be seen today. The fronds, or leaves, called lau hāwane were used by the early Hawaiians for thatching and more recently as plaiting such as papale (hats) and fans. Photo Credit: David Eickhoff © 2007

  • Date Inducted in National Collection:

This beautiful palm tree species may be slow growing, but its majestic fronds and brilliant clusters of green, white, and yellow flowers are worth the wait. Not only are its flowers impressive, but its fronds show various shades of olive and blue-green on top and silvery-bronze on the bottom. Thanks to their numerous arthropod pollinators, including bees, black olive-shaped fruits are produced by this palm in the summer months. Early Hawaiians utilized all parts of the trees in this genus for the improvement of their daily lives: the hard wood of the trunk for spears, immature fruits for food, and fronds for thatching roofs. Today, the fronds are used for fashionable hats and fans while the seeds are collected and made into a lei.
