Similar species
Scentless Chamomile (Tripleurospermum indorum) has similar looking flowers but leaves are very different and can easily ditinguish the two.

Shasta daisy/Alaska Shasta Daisy (Chrysanthemum maximum/Leucanthemum x superbum 'Alaska') a more robust plant with larger flowers, is a cultivar that originated from Oxeye Daisy and was originally sterile, but can revert back to being fertile. If Shasta Daisy is escaping from ornamental plantings, it has become fertile, treated then as Ox-eye Daisy.
