Hedge Parsley - Torilis (Invasive/Eradicate)
All Torilis parsley have been introduced in Wisconsin and are considered invasive.
This is a wispy plant (in the carrot family) with 5-parted, white/pink flowers in small, loose, compound umbels. The leaves help to identify it. The leaves are alternate, compound, fern-like, 2-5 inches long and slightly hairy.
Habit include waste ground, disturbed sites, thickets, roadsides, railroads.
Spreading Hedge parsley (Torilis arvensis) and Erect hedgeparsley (Torilis japonica) are both very similar. One difference is that Torilis japonica has 2 or more pointed bracts at the base of each umbel, otherwise the two plants are very much the same.
Other names (Torilis arvensis) include: Spreading Hedge parsley, Canada hedgeparsley, hedgeparsley.
Other names (Torilis japonica) include: Erect hedgeparsley, Upright hedgeparsley, Japanese Hedge Parsley,
