(2) Upland Cress, in two varieties Barbarea vul- 

 garis and B. prcecox is known as Broad-leaved Winter, 

 American, Belleisle, Hardy, and Scurvy Cress. It is a 

 hardy plant; the seeds may be left in the ground over 

 winter, to sprout in the spring. It resembles Water 

 Cress in form and flavor; like garden Cress, it is best 

 grown as a fall or spring salad, the leaves becoming 

 tough and bitter in summer. As the leaves lie flat on

Soil. Any good garden soil, not too dry. 



Distances. Drills one foot apart. 



Depth. About one-half inch. 



Sow as soon as the ground is fit, and again in mid-

 spring start. 



Thin to four to six inches. 



Pick at about four inches, and again as the leaves 

 grow.

 or at the edges of springs, but with care may be cul-
