Management brief
Andropogon virginicus
Poaceae · 21 Hawaiian specimens · 1924–2019
What this means for control work
Fruit has been recorded Aug to Dec. Treat before it, not during.
This window comes from specimens collected outside Hawaiʻi — 30 of them — because only 2 Hawaiian specimens carry a scored date. It shows the shape of the species’ cycle. It is not a Hawaiian calendar, and it should not be used as one for scheduling.
Wind-carried. Distance depends on the day rather than on an animal, and a plant left standing through its fruiting window seeds the neighbourhood.
