Scaevola taccada is a dense, spreading shrub that generally grows up to 3 meter in height. The light green leaves are somewhat succulent with a waxy covering and are alternately arranged along the stem. The blades are elongated and rounded at the tips, 5 to 20 cm long and 5 to 7 cm wide and the edges are often curled downward. The flowers are white or cream colored, often with purple streaks, 8 - 12 mm long, and have a pleasant fragrance. They have an irregular shape with all five petals on one side of the flower making it appear to have been torn in half. The flowers grow in small clusters from the leaf axils near the ends of the stems. The fruits of Scaevola taccada are fleshy berries. They are white, oblong, and about 1 cm long. The seeds are beige, corky and ridged. The inside of the fruit is spongy or corky and the fruits are buoyant. They can float for months in the ocean and still germinate after having been in salt water for up to a year. One study showed that the seeds germinated best after 250 days in salt water.

The pleasantly fragrant flowers and the seeds are used for making leis in Hawai'i.
Scaevola taccada naturally occurs on tropical and subtropical coasts from the Indian ocean eastward to Hawai`i. Naupaka is common in hot dry coastal areas on most of the Hawaiian islands except for some of the Northwest islands. (Wagner, Warren L., Darrel R. Herbst, and S. H. Sohmer. 1990. Manual of the flowering plants of Hawai'i.)
Flourishing along the coastline, the myth-inspiring Naupaka grows a unique half-flower, causing ancient Hawaiians to believe that it is the incarnation of an ancient lover separated from its mate. There are many versions of the story of the Naupaka flower and how it came to look as if it were torn in half. In one version, the Princess Naupaka is forbidden to marry her true love, a fisherman. As they part ways forever, she takes a flower from the lei on her head, and tears it in half, symbolizing their separation. She returns to the mountains where she grew up and the fisherman returns to the sea. (Koob, Gregory A. 2000. Lovers Separated: the Beach and Mountain Naupaka.)
