[MAIPC] Corydalis incisa: be on the lookout

Wed Apr 6 16:00:42 PDT 2016

Thanks, Milo. One point for us all is that the Plants fact sheet does not
have any locations for this plant outside of NY State, and we should all
look into that. Does anyone know how one goes about "registering" a plant
location with them?  And I suppose that there is some sort of review process
that goes on before any data point is noted. I think I recall that last
spring someone reported this plant near Wolf Trap in Nrn. Va. Here is a link
to the Digital Atlas of Virginia Flora with a brief note about the plant

Purple or white flower color looks like a pretty clear identifier -
according to Flora of Virginia, we only have one native Corydalis: the much
smaller yellow-flowered C. flavula. C. sempervirens has pink flowers ( & has
been renamed Capnoides sempervirens). Then there is Fumaria officinalis with
round seedpods - and it isn't native.

Ruth,

Just to be sure.. How do you know that this is incisa? There are a lot of
native Corydalis as I'm sure you know... Some look like this. I just want to
be sure the identification is correct.

Thank you!

Last year around the end of April I went looking for possible Corydalis
incisa along Red Bud Creek, near my home in Albemarle Co. VA. I found
probably 40 plants in bloom and starting to go to seed. I pulled up all
those I saw and flagged the area. This year I went back on April 3 and found
about 15 plants in bloom nearby, but not yet going to seed, and pulled them
all and again flagged the area.

In the last several days I have heard of two more infestations in Virginia,
one more in Albemarle Co. and one in Madison Co., both in extensive private
native plant gardens. I don't know if the plant hitchhiked in with another
plant purchased from a supplier or whether the owner planted them without
realizing that they could be very invasive; I will investigate that.

I don't think I can attach a picture, but here is a link to a photo

And here is a link to a plants profile
