| − | + | Lettuce. The lettuce plant is botanically Lactuca saliva (which see), which is probably derived from Lactuca Scariola. It is an annual with milky juice, and has been greatly developed for its root-leaves These leaves, much enlarged and modified, comprise the most popular of the plant salads. It has been in cultivation for more than 2,000 years, according to De Candolle. The varieties are many; in 1889, "Annals of Horticulture" listed 119 varieties offered by American dealers. The two general forms are the head lettuces and the cluster or open-leaf lettuces. There are also spring lettuces and summer lettuces, the latter being developed to withstand more heat, for lettuce usually thrives best in the cool weather of spring. Of late years, kinds specially adapted to forcing have been secured, as the growing of the crop under glass has now assumed large proportions. | |
The lettuce plant is quite hardy to cold, comes quickly to edible maturity, is not much subject to disease or insect injury and, though it quickly succumbs to dry hot weather, is generally of the easiest culture. Even a farmer's wife, who, because of household cares, cannot take the time to plant a garden or even to gather and prepare a mess of peas or beans, can make and care for a planting of lettuce, and a few heads cut in the early morning and placed where they will be kept cool are a most appetizing addition to the noonday meal. From 1 to 2 yards of row to a person should yield an abundance for as long as a single planting is usable and a family supply may be grown in the smallest village yard or even on the back of a city lot; and, because of coming to the table in better condition, may be superior to any obtainable from the market. | The lettuce plant is quite hardy to cold, comes quickly to edible maturity, is not much subject to disease or insect injury and, though it quickly succumbs to dry hot weather, is generally of the easiest culture.

Varieties differ greatly in adaptation to cultural conditions, some giving fine returns when grown under glass but are hardly usable when grown in the open garden. They also differ greatly in color, tenderness and other qualities of the leaf. In some varieties, like the Prize Head, the leaf is mottled with red and brown and so tender that they are often so broken and torn apart by a heavy rain as to be unsalable, while the light green more tender-looking but really tougher leaves of a nearby planting of Grand Rapids are uninjured. There are varieties that form very broad white midribs which, when the green portion of the leaf is cut away, make quite as beautiful salad for table decoration or to eat from the hand as the finest celery or witloof. | Varieties differ greatly in adaptation to cultural conditions, some giving fine returns when grown under glass but are hardly usable when grown in the open garden.

Many successful growers in planting the Grand Rapids do not cover the seed at all except by washing over a little earth with a watering-pot and then shading with a board supported 1 or 2 inches above the row and removed as the plants germinate and start into growth.

Hundreds of different varieties and strains have been developed, varying greatly in habit of growth and character or product, ranging from those with but a few upright-growing narrow, smooth, thin leaves, and which soon shoot to seed, to those with many thick broad, smooth, crumpled or savoyed leaves, either clustered together, or overlaying each other so as to form a round head like that of a cabbage.

The growing of lettuce seed.—In few vegetables is the satisfaction from a planting more dependent upon the varietal character and quality of the seed used, and fortunately the quality of most of that on the market is very dependable. Up to about 1865 most of the seed came from Europe, though comparatively small quantities were grown in Connecticut, New York and Michigan. About that time persons began to grow lettuce seed in California and the amount produced has increased until today not only the greater part of that used in America is grown there but large and constantly increasing quantities are sent to Europe. While small plantings of especial lots, of which little stock seed is available, are grown from started plants which are set in place in the field, the greater part of the crop is grown from seed sown in rows about 30 inches apart and the least typical plants pulled out until three to five plants to the yard are left.
