Open this record in the interactive AtlasAbout Hilo holly
Hilo holly (Ardisia crenata) is recorded as an established shrub on Kauaʻi. A small upright shrub reaching about 1.5 metres, with branching concentrated in flowering shoots. Its firm alternate leaves have wavy, rolled edges. Small pale flowers are followed by round red fruits about 5–8 millimetres across; these distinguish it from mature black-fruited Ardisia elliptica. Shade-tolerant shrub capable of forming dense understory stands and reducing light available to other vegetation. Reported effects elsewhere do not establish a measured Kauai effect.
Kauaʻi evidence
Established island occurrence follows the Bishop Museum checklist. Diagnostic morphology follows Smithsonian Hawaiian Flora; accepted identity follows Kew WCVP. Generated imagery is not occurrence evidence. Proposed monitoring endpoints are not reported observations, measured effects or causal findings.
