VARIETAL DESCRIPTIONS OF VEGETABLES 
KEYSTONE SEEDS 
♦ 
MUSTARD 
Brassica juncea 
Although mustard is today well known and commonly used for greens throughout the South, 
we feel it is destined to become even more popular as people practice the use of successive plantings. 
Try canned mustard greens offered by the grocer—they are really good.

CHINESE BROAD LEAVED or Elephant's Ear MAPLE 
A commonly grown mustard; a hardy and vigorous grower; produces large, broad, 
oblong, smooth, serrate, medium dark green leaves in a rounded mid-rib, tender 
and ecellent for greens, either as a salad or for boiling. This variety does not shoot 
seeders quickly. Seeds reddish brown. 
FLORIDA BROAD LEAVED MANTA 
A fine, large, rapid growing type, with bright medium green, thick broad, oval, smooth, 
large, slightly tooth-margined leaves with a distinct flattened whitish mid-rib. It is 
extensively grown because of its fine edible qualities and is not quick to bolt seeders. 
Seeds reddish brown. 
FORKHOOK FANCY CURLED or Ostrich Plume MARCH 
A very finely curled plume like mustard. Very desirable for greens and salads for 
its excellence in quality and for being so slow in bolting seeders. A vigorous, upright 
plant, rich bright green and deeply fringed leaves. Seeds reddish brown. 
SOUTHERN GIANT CURLED (Long Standing) MARRY 
The leading mustard. It is unquestionably the most popular and widely known. It 
represents a high standard in quality and attractiveness. Plant large and upright in 
growth. Leaves, large, long oval, crumpled, curled, and fringed on the margins, bright 
medium light green in color. Seeds reddish brown. 
YELLOW or White London Alba MASON 
An early sort, grown principally for its light-colored seeds, which are used for making 
table mustard. Plant rather dark green, with smooth, deeply cut leaves. Not used 
for greens, as it bolts seeders very early. 
TENDERGREEN or Mustard Spinach (Komatsuma) MEDAL 
A recent introduction of Oriental origin that has outstanding merits. It is an excellent 
sort because of its resistance to hot, dry weather and delicious flavor resembling 
blended spinach and mustard. Leaves, rich dark green in color, large oblong, smooth, 
with slender whitish center ribs. Does not bolt seeders quickly.
