Under the name of cress there are two forms, the water cress and the
upland cress. The upland cress, sometimes called peppergrass, is easily
grown from seed sown in drills a foot apart. As the plants last but a
short time, it will be necessary to make a sowing every few days if a
continuous supply is desired.
Water cress can be grown all the year in small open ditches containing
running spring water. It is best and most easily produced in water
from rather warm springs in limestone regions. A sufficient supply for
family use can be grown in a small spring-fed brook, and the plants may
be started either from small pieces of plants or from seed. Cress is
used in salads, to which it imparts a pleasant pungency.--(F. B. 255;
