Common Cudweed is not easily confused with other wild plants on this web site.

This is an erect annual which grows to about 50cm tall, bearing spherical clusters of small flowers on stems that fork into 2-3 branches at the top. Each flowerhead is made up of 20-40 tiny yellow florets that are surrounded by narrow bracts, the outer woolly and the inner bristle-tipped. The stems leaves are erect, wavy-edged and clasping the stem; they are also woolly. Flowering in July and August, this species grows on sandy grasslands, arable fields and dunes. It is a rare, native species, formerly known as Filago vulgaris, and it belongs to the Daisy or Asteraceae family.  


I first saw this in Yoletown, County Wexford in 2019 when shown it by Paul Green, BSBI Vice-county Recorder for Counties Waterford and Wexford.
