Habit Foliage Flower Seedlings
Mayweed chamomile (Anthemis cotula) flowers in clusters on solitary
flower heads at the terminal of stems.
Like other plants in the family Asteraceae, flower heads are actually
clusters of disk and ray flowers. On mayweed chamomile, the white
petal-like structures are actually the corollas of white ray flowers. So
in the picture below, the single flower head in focus has 13 distinct ray
flowers surrounding the smaller, yellow disk flowers. The disk flowers
form the center of the flower head and are numerous.
If you see these daisy like flowers on a plant with very dissected foliage,
you can probably be certain that it's mayweed chamomile.
Flower heads are numerous on a single plant.
