Ilima

Scientific Name: sida fallax

Hawaiian Name: Ilima

Ilima is a common plant that thrives in sunny and hot conditions. This plant was prized for it’s beautiful flowers that were strung into delicate leis. This is the offical flower for Oahu. However, many people don’t know that this flower is actually edible and can be eaten in salads.

Hawaiian Rockwort

Scientific Name: Nototrichium sandwicense

Hawaiian Name: Kului

This native plant has silvery leaves and is very popular among landscapers. This plant is drought resistant so it’s good for those looking to create a xeriscaping garden. The Hawaiians packed the flowers and wood of this plant in bamboo and would toss it over a cliff to create something similar to a firework display.

Coconut Tree

* Polynesian Introduced

Scientific Name: Cocos nucifer

Hawaiian Name Niu

This is probably  both the most recognizable palm tree and Hawaiian plant in the world.  The  Hawaiians used this plants’ fronds extensively for weaving.  The fruit can also be eaten, in green form as a jello, or brown form as a tough meat.  Incredibly, the fruit is edible  for up 5 months while on a tree. Unlike in many TV shows and movies, coconuts actually have a fibrous husk surrounding the fruit that must be removed before cracking.

Milo

* Polynesian Introduced

Scientific Name: Thespesia populnea

Hawaiian Name: milo

This common tree can often be found in parks and provides solid shade. It was used by the Hawaiians to food utensils and containers because it left no bitter aftertaste. The bark also made a poor quality cordage and it’s fruit produced yellow and green dye. It’s not really clear why the Hawaiians brought this plant considering that it doesn’t appear to have any unique or essential uses.

Hau

* Polynesian Introduced

Scientific Name: Hibiscus tiliaceus

Hawaiian Name  Hau

The Hau plants normally looks like a twisting mess of curved branches and 5 pedaled flowers. These curved branches were often used in creating outriggers for canoes due to it’s shape and light weight. The plant was and still is very common and it’s bark was the primary plant used by the Hawaiians for cordage. However, the wood proved even more valuable to the Hawaiians as they would vigorously rub a smaller piece in a grove of a larger Hau branch to create fire. ( Photo by Forest and Starr)

Hala

* polynesian introduced

Scientific Name: Pandanus tectorius

Hawaiian Name: Hala, Pu Hala

This plant is easily recognizable through its droopy leaves and the pineapple like appearance of it’s fruit. The mangrove like bottoms allows the hala to filter out small amounts of salt water and survive well on the coastline. The Hawaiians main use of this plant was it’s leaves. The leaves were used to weave, mats hats, plates, blankets, bags but most importantly they wove the sails of their voyaging canoes that carried them the thousands of miles to and from Hawaii.

Hawaiian Cotton

* At Risk

Scientific Name: Gossypium Tomentosum

Hawaiian Name: Ma’o Huluhulu

These shrubs have large hibiscus like flowers, but produce relatively short cotton fibers that were not useful for cordage or cooking. However the hairs were used for tinder and used similarly to a cotton swab or Q tip. The plant is also resistant to many pests and disease of commercial cotton and has been cross bread with commercial types  to create disease resistant hybrids( Image by Forest and Starr Kim)

Hawaiian Poppy

Scientific name: Argemone glauca

Hawaiian Names:  Kala, Naule, Pua  Kala

This plant with it’s jagged silver leaves is one of the few native plants to have thorns. This is also one of the few native plants to be poisonous causing deep sleep in small concentrations and seizure and death in higher concentrations. The Hawaiians however used it’s poisonous sap as a narcotic and analgesic for surgeries.

Ohai

* Endangered

Scientific name: Sesbania Tomentosa

Hawaiian name Ohai

This endangered plant has soft silverly leaves because of the thousands of tiny hairs that cover this plant. These hairs help protect the plant from the heat and help trap tiny particles of moisture. The Ohai has the ability to gather nitrogen from the air and defuses it in the soil creating a organic fertilizer for nearby soil. The salmon colored flower is fragrant and was prized for lei making.
