About Hāhā
A largely unbranched shrub with broad glossy leaves, pale undersides and maroon to purple stalks and lower midribs. Hairy curved flowers are dark purple, with pale inner lobe tips. Rounded maroon to dark-purple berries have orange flesh and contain tiny dark seeds. This native shrub is a component of Hawaiian vegetation. Monitoring mature plants, new recruits and occupied cover can assess persistence and replacement. The reviewed accounts do not establish a measured Kauaʻi population trend or quantify an ecosystem effect.
