CHICORY, Cichorium Infybus, L. 



Other English names : Wild Chicory, Wild Succory. 



(Noxious : Dom.) 



Introduced. Perennial from a long deep rootstock. Stems 2 to 3 feet 

 high, branched, hairy below. Root leaves, closely resembling those of the 

 Dandelion, 6 to 8 inches, spreading on the ground, runcinate pinnatifid or 

 dentate ; midribs hairy beneath ; upper leaves glandular ciliate on the mar- 

 gins, clasping, at base. Flower heads bright blue, nearly 2 inches across, 

 composed entirely of strap-shaped flowers, usually closing by noon, in sessile 

 clusters of three or four together along the almost leafless stems. Seeds 

 [Plate 54, fig. 21 natural size and enlarged 8 times] inch long, dark 

 brown or straw-coloured, mottled with brown, wedge-shaped, obtusely 3 to 

 5-angled, some seeds being much curved ; the surface is grooved and ridged 

 from top to bottom and roughened crosswise with minute close raised and 

 waved lines ; at the top, surrounding the apical scar, is a fringe of short 

 flat white bristles. 



Time of Flowering: July to frost; seeds ripe in August. 

 Propagation : By seeds or shoots from the roots. 



Occurrence : Throughout Eastern Canada, most abundant in the Pro- 

 vince of Quebec. 



Injury : A troublesome weed in rich low land and in pastures. Seeds 

 often found among crop seeds, particularly of clovers and grasses. 



Remedy : A short rotation of crops, as for Canada Thistle. Chicory is 

 not often seen in good farming districts except as a wayside weed.
