Sawtooth Blackberry
Introduced and now reproducing on its own in the wild.
Rubus argutus is a North American species of prickly bramble in the rose family. It is a perennial native to the eastern and south-central United States from Florida to Texas, Missouri, Illinois, and Maine. Common names are sawtooth blackberry or tall blackberry because of its habit of growing up to 2 meters (80 inches) in height.

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.
