The name is misleading as it is a non-heading variety. Very early, quick 
growing, making a lot of good eating leaves of excellent flavor. Leaves 
are light green with very ragged brown edges. A most popular variety 
with home gardeners. 
SALAMANDER OR BLACK SEEDED TENNIS BALL 68 Days 
Leaves medium green and crumpled. Head globular, hard and buttery, 
and of good flavor. One of the most popular with market gardeners be- 
cause it makes heads in hot weather when other varieties fail. 
ROMAINE OR PARIS WHITE COS, W.S. 77 Days 
The best known and most popular Cos variety in America. It is medium 
large, medium green, and forms a good, well folded head of fine quality, 
which blanches readily. 
SLOBOLT . 43 Days 
U. S. Dept. of Agriculture introduction. Similar in type to Grand Rapids 
but with unusual resistance to bolting in warm weather. 
WHITE BOSTON OR UNRIVALLED, W.S. 76 Days 
Similar to white seeded Big Boston but with leaves slightly lighter green 
and free from a brown tint; heart buttery, yellow; of excellent quality. 
Highly desirable for nearby markets 
CuLturE. Mustard is grown for its seed which is used for flavoring 
or medicinal purposes or grown for its leaf which is used in salad or 
cooked like spinach. Sow mustard as soon ag the soil can be worked 
in spring and every three weeks for a succession, or in the South it may 
be sown in the fall for early spring greens. Cover the seed lightly in 
twelve to eighteen inch drills. Cut the leaf when not over four inches high. 
Number of days given iy from planting to cutting.

crumpled; medium green; scalloped at edges. Seed reddish brown in color. 
FLORIDA BROAD LEAF 40 Days 
Leaf very large, broad, long oval with a smooth saw-toothed edge and 
broad white mid-rib; bright green in color. Makes a strong, quick growth, 
spreading out somewhat more than other smooth types. Holds well in 
hot weather. Seed dark brown in color. 
SOUTHERN GIANT CURLED 35 Days 
Leaf very wrinkled, blistered and curled at the edges; light yellowish- 
green in color. Very prolific. Holds fairly well for spring planting but 
is mainly used in the south as a winter greens crop. Seed dark brown 
in color. 
LARGE SMOOTH LEAF OR BLOOMSDALE 35 Days 
An excellent variety with very large, green, comparatively smooth leaves 
borne well above ground. Quick growing, fairly upright when young but 
becoming somewhat spreading when matured. Preferred by many be- 
cause it is more easily prepared for the table than the rougher leaved 
varieties.
