[MAIPC] biological control permitted for release

Fri Mar 6 12:31:08 PST 2020

I collected this species in Greene County, PA, in 2018. It appears to have been a county record. It was growing along a road and not obviously behaving in an invasive way, but I did not examine adjacent areas.

I'm not aware of any Mid-Atlantic state, local or regional invasive plant lists that include either Lepidium draba or L. appelianum. Has anyone else found a Mid-Atlantic list with either of these two species?

Marc,

I don't see Mid-Atlantic records for Hoary Cress (under any synonym) in iMap, EddMaps, GBiF, or iNaturalist. I'm guessing they will be forthcoming.

CAUTION: External Email

Hoary cress is now invasive in our region and there is a biological control permitted for release. Also 2 reports of Globe-podded hoary cress in Pennsylvania.
