Cambridge, UK: Cambridge University Press, 254-301. 544 pp. While the characters differentiating C. debeauxii from C. jacea and C. nigra might be challenging to use, and while populations of C. debeauxii show a wide range of morphological variation, evidence suggests that this hybrid occupies a somewhat different niche to either of the parents - in particular, wet meadows and riparian habitats (Roché and Roché, 1991). Comments: Meadow knapweed is a fertile hybrid between black and brown knapweeds. It is native to Europe but it is known on other continents as an introduced species and often a noxious weed.. Great Basin Naturalist, 52(2):185-188. Phytophagous insects which will use C. debeauxii as a host plant can be found in the Natural Enemy table (Wilson and Randall, 2005).

Meadow knapweed is a deep-rooted perennial, growing each year from a woody root crown. Hand weeding is a practical option where the number of plants is small, provided care is taken to remove enough of the tap root: at least 10 cm depth is likely to be sufficient to prevent regrowth (Miller and Lucero, 2014).
