Cypripedium reginae............on Cape Cod these are relatively
prolific.......in the springtime one of our walks takes us thru an area that
must contain at least a thousand of them......on one small hillock alone
there has to be in excess of 250........last year we discovered another
three around the our house.....we only have about half a dozen or so...I
say 'about' as we periodically see another seedling popping
up...........they are just left alone to do their thing. HW.
