Grindelia Willd.

Grindelia is a taxonomically complex genus of about 30 species (Mabberley 2008). All are native to the New World and chiefly concentrated in warm-temperate regions. Several species are cultivated as ornamentals in Europe (Cullen 2000, Jäger & al. 2008) but none has been recorded as an escape in Belgium so far.
