the edges of the leaves shall be permitted, provided 
these edges are not dried. 
In order to allow for variations incident to proper 
grading and handling, not more than 10 percent, by

shall have the same general character of growth and 
color; that is, curly-leaf type and distinctly smooth- 
leaf types shall not be mixed, and distinctly purple- 
type plants shall not be mixed with green- or blue- 
type kale. As blue-type kale often shows a purplish

may not show this color, such a mixture shall be con- 
sidered as one type. 
“Well trimmed” means that the butt is trimmed 
off to not more than three-fourths of an inch from 
the point of attachment of the outer leaves and that 
yellow, discolored, dried, or otherwise damaged leaves 
which materially affect the appearance of the plant 
have been removed. 
‘Damage’ means any injury or defect which ma- 
terially affects the appearance, or the edible or ship-
