The first set is from the Ravine and Butterfly Gardens in Central Park (map). A few of these gave me a bit of trouble to identify.
The second set of flowers are in the Conservatory Garden. I am stuck on the last two. Does anyone know what they are called?
A friend, Fritz, from the Butterfly Club in NYC helped me identify the red daisy like flower. It is Great Masterwort (Astrantia major ‘Rubra’).
