17 flowering · 16 fruiting annotations · iNaturalist · fetched Jul 2026
■ flowering (peak December)■ fruiting (peak September)
This is an inference, not a schedule. The curve reflects when observers annotated flowering and fruiting — which tracks observer effort as well as plant behavior, and pools all elevations and islands into one signal. Hawaiʻi’s microclimates vary enormously; a species may fruit in January at sea level and June at elevation. Use this to know when to look, then look.
