Scentless chamomile, also known as mayweed, scentless mayweed or daisy, has white daisy-like flowers and its finely divided fern-like leaves. The flowers grow individually at the ends of smooth, erect branches.
Plants range can grow up to 3 feet in height and tend to be bushy when not subjected to competition. The seeds are dark brown, 2 mm long, rectangular and have prominent wing-like ribs that are paler than the kernel. The root system tends to be large and fibrous but does not run or creep.
Scentless chamomile can be mistaken for ox-eye daisy. These plants can be differentiated by their leaves, as scentless chamomile has finely divided leaves while those of ox-eye daisy are entire and notched but not divided. Scentless chamomile has several to many flowers on each flowering stem while ox-eye daisy has a solitary flower on each flowering stem.
