Meet Hieracium kalmia – Canada Hawkweed. One of seven species of hawkweed that grows
in Wisconsin.
Technically a
non-native this species has a cool feature. The flowers close at night and on cloudy days.
The common name - Hawkweed - came from the mistaken
belief that hawks ate the flowers to improve their vision.
Like related members of the aster family
this variety is now naturalized all over North American and all over here.
