[MAIPC] New EDRR species in the Mid-Atlantic

[Farrah, Mary]

Hi All,
I got an email from a DC resident, Larry Haller, who has Corydalis incisa growing aggressively growing in his yard. According to this link<http://blogs.nybg.org/science-talk/2014/07/detecting-an-invasive-plant-before-its-too-late/> it's a big  problem in NY. It occupies the same niche as fig buttercup.

The USDA only lists it occurring in NY, but now that there's been multi-state communication about this species, we're finding that it is more wide spread in this region than previously thought. Larry posted photos of this plant on some local listservs and found someone from a nearby neighborhood has it growing in their yard (yet to be verified). NY says that Philly reported a sighting. There was also a potential sighting in Northern Virginia. We should add it to our EDRR list. Has anyone else encountered this species in their region?
