[MAIPC] lesser celandine control??New EDRR species in the Mid-Atlantic

[Kathy Michels]

Speaking of lesser celandine it has taken over everywhere in our local stream valley parks (Sligo Creek and Northwest Branch especially) and is destroying the foremerly extensive bluebell fields on Northwest branch.

How can we control lesser celandine?? Pulling is counter productive  and the parks are not likely to nor should they do whole sale spraying. So what to do??? On my steamside property ive actually been  digging up and disposing of the mats of plants along with the soil the bulbs are in. But not doable for huge fields of it.

I may have found it in the flood plain of a creek very near where I live
(Charlottesville, VA), but I want that sighting to be verified. It looks a
lot like Fumitory, Fumaria officinalis, but it's seed pods are elongate
while those of Fumitory are "globose to weakly obovoid" (per Flora of
Virginia).

 

Any tips other than flame-weeding?

Corydalis incisa can jump around your garden.

My husband has been flame-weeding patches of it in our yard (Clarksburg,
Maryland)for several years.

I think it would occupy the same niche as lesser celandine, but that it
could also grow in somewhat drier, partially shaded places very well.

However, I haven't seen it in any natural areas to date, and I do look for
such things J

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-befo
re-its-too-late/>  it's a big  problem in NY. It occupies the same niche as
fig buttercup. I'm sending this email sans photos, so that this third email
attempt will actually make it to you all. Check the link above for photos.

 

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?

If I don't promptly respond to your email it means I'm working in the field.
I will reply when I return to the office.
