Hi there,

         Mary, your plant description sounds like Canada Burnet, 
(Sanguisorba canadensis), which is an herbaceous perennial in the 
rose family.  There are photos in John Maunder's "Digital Flora of 
Newfoundland and Labrador", which you can find on the web.  Canada 
Burnet, as the species name suggests, is a native to the northeast, 
found in Newfoundland and Labrador, as well as in Nova Scotia and 
parts of New England.  It is uncommon in mainland N.S.;  the only 
place where I can remember seeing it is at Scot's Bay along the road 
before the start of the Cape Split trail.  It is more common in 
northern Cape Breton and the island of Newfoundland. I've seen it in 
the Cheticamp area, and along the Great Northern Peninsula.

         Cheers,

         Patricia L. Chalmers
