Anise thrives best in a light, moderately rich, and well-drained loam
which has been carefully prepared before planting. It is grown from
seeds, which are usually sown early in the spring directly in the
field, since the seedlings are unfavorably affected by transplanting.
The seeds, which should not be more than 2 years old, are sown thickly,
about two to the inch, and covered one-half inch deep. Since the plants
develop very slowly, seed should not be sown in weedy soil. When the
seedlings are 2 to 3 inches high they are thinned to stand 6 inches
apart in the row. The rows may be 18 inches or 3 feet apart, depending
on the cultivation intended. An ounce of seed should sow a row 150 feet
long, and about 5 pounds will plant an acre when the rows are 3 feet
apart. The plants should receive frequent and thorough cultivation
throughout the growing season.
About three months from the time of planting the plants will blossom,
and a month later the seed should be matured sufficiently for
harvesting. As soon as the tips of the seeds turn a grayish green color
they should be harvested, for if allowed to remain exposed to the
weather they quickly turn brown or blacken. The plants may be pulled by
hand and stacked, tops inward, in heaps about 6 feet high, or they may
be mowed and at once built up into cocks of the same height. In about
four or five days the seed will have ripened, after which it should be
thrashed out and thoroughly cleaned.
Yields of anise seed are quite variable, since the plant is very
sensitive to unfavorable weather conditions. In a good season from 400
to 600 pounds per acre may be reasonably expected. The prewar wholesale
price usually ranged from 6 to 8 cents a pound. The prices in June,
1920, ranged from 19 to 30 cents a pound. During the war the average
annual importation of 500 tons was reduced to about 180 tons.
ARNICA.
Arnica (_Arnica montana_) is a herbaceous perennial plant of the aster
family, native in northern and central Europe, where it thrives in the
cool climate of the mountain meadows and upland moors. The flowers,
leaves, and roots are employed in medicine.
Arnica requires a marshy soil, abundant rainfall, and a cool climate
for its best development. It is propagated by divisions of the roots
or from seeds sown either in the fall or the spring. Seed may also be
sown in August in a seed bed and the plants transplanted the following
spring to stand about 18 inches apart in the row. The flowers may be
harvested the second year and the roots after three or four years.
Arnica is not produced commercially in the United States, and the small
quantity imported annually is apparently sufficient to meet the market
demands. Its cultivation presents many difficulties, and efforts to
grow it in the milder portions of this country have generally proved
unsuccessful.
