Management brief
Erigeron karvinskianus
Asteraceae · 25 Hawaiian specimens · 1930–2019
What this means for control work
Fruit has been recorded Jun to Jul. Treat before it, not during.
This window comes from specimens collected outside Hawaiʻi — 14 of them — because only 0 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.
