Introduced and now reproducing on its own in the wild.

Oenothera stricta, the fragrant evening primrose (a name it shares with other members of its genus), is a species of flowering plant in the family Onagraceae. It is native to the Desventurados Islands, Chile, and southern Argentina, and it has been introduced to many locations around the world. The unimproved species is available from commercial suppliers, as is a cultivar, 'Sulphurea'. The Royal Horticultural Society considers both to be good plants to attract pollinators.

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.
