Pilosella glomerata (weed)
Pilosella glomerata (weed) (Froel.) Fr.
This species of dandelion-like plants is native to Europe and surrounding regions, but is invasive in parts of North America (first record 2001, see Wilson et al., 2006). In Europe, it is common in central and eastern parts. P. glomerata is similar to Pilosella caespitosa and both species are difficult to distinguish.
Synonyms:
Hieracium glomeratum
