Goatsrue

[Timothy A. Block]

We have a small infestation of the U.S. federal noxious weed Galega
officinalis (Leguminosae), common name goatsrue, here at the Morris
Arboretum in Philadelphia.  Until very recently, this plant was known to
USDA/APHIS in the U.S. only from several sites in Cache County, Utah where
large investments in time and money have gone toward attempted
erradication.  It came as quite a shock to the folks at USDA that G.
officinalis had become naturalized in Pennsylvania.  This native of the
Middle East is toxic to livestock, hence the noxious weed designation.

We are also aware that, in spite of the plant's status as a noxious weed,
G. officinalis seed is available in the herbal medicine trade (several seed
sources were found on the web).

This brings me to my question for my fellow North American plant hunters.
Are any of you aware of naturalized occurrences of Galega officinalis
anywhere in the U.S. other than in Utah?  If so, any information on
location, habitat, numbers of individuals, whether specimens were
collected, etc. would be valuable.

Thanks for your help.
