Introduced and invasive status

Invasive in Ohio: Ohio Department of Agriculture (opens in a new tab)

Also listed

Ohio law lists it as an invasive plant: not native to Ohio, and causing, or likely to cause, economic, environmental or human health harm.

iNaturalist's volunteer curators list it as introduced in their Ohio checklist.

US-RIIS assesses a species as invasive when it causes, or is likely to cause, harm there, or is at least locally abundant and harmful ecologically, economically, or to health.

Status: Simpson A, Sellers E, Pagad S (2023). United States Register of Introduced and Invasive Species (US-RIIS), ver. 2.0. U.S. Geological Survey, https://doi.org/10.5066/P9KFFTOD (opens in a new tab)

Reported in flower

No flowering season shown here. Most records come from a single year, so a season is not shown yet.

Reported in fruit

No fruiting season shown here. The weeks are still too uncertain to show a season.

What these results show

These results show when people recorded a species, not when or where it occurs. Missing weeks and low counts do not mean absence or scarcity, and counts are not abundance. Contributed records reflect where, when and what people chose to observe.

Identification

How to identify it
