They are part of the Aster family and range in colour from orange to yellow to red.
Gardeners and landscapers consider most hawkweeds to be a troublesome plant, but these weeds play an important role in the environment. Hawkweeds are pollinated by several types of moths, including the lime speck bug, the Hebrew character and the dot moth. The fruit and seeds of these perennials are an important source of food for animals ranging from the large yellow under wing moth to the common rabbit.
What first caught my attention to this plant is what it looks like before it blooms. Very knobby looking almost like a crazy bug eye! In this part of Ontario this flower is common. To me, it's uncommon and quite beautiful.
