Coastal sea hibiscus tree confirmed growing on Kauaʻi shoreline

iNaturalist: cmwils21

Native Plants

If you're walking a Hawaiian beach and spot a tree with heart-shaped leaves and yellow flowers that turn orange by afternoon, you're likely looking at sea hibiscus, a plant Polynesians brought across the Pacific for cordage, canoes, and medicine long before Western contact.

Someone out in Poʻipū, Kauaʻi spotted a sea hibiscus tree and logged it on iNaturalist, where other naturalists confirmed the identification, making it a verified 'research-grade' sighting. Sea hibiscus is a coastal tree with big yellow flowers that fade to orange and then red before falling, and it's been a fixture of Pacific Island shorelines and cultures for centuries.
