BULB (bulb). A bulb is a thick, fleshy bud that usually grows underground. In many plants, such as the tiger lily, it grows above ground, in the spot where the leaves branch from the plant stem. Bulbs are of two types: the scaly and the tunicate. The scary type bulb as in most lilies is made up of a short central core inside of thick, fleshy, scale like leaves. The tunicate bulb, such as the onion, has fleshy leaf bases in smooth and continuous layers. If an onion is cut in half, the inside looks like thickened bands or circles of tissue. Roots generally grow from the base of the bulb. The bulb serves as a storage place with enough food and water to supply the plant during winter or a dry period.

The bulb is also a storehouse for new stems, leaves and flowers, after the plant first flowers. In fact, the bulb has in it a new stem and often the beginnings of flowers and leaves as well. These are protected within the bulb by the bulb scales. These scales or leaves are a food storehouse for the plant. The food stored in the bulbs during one season is used for the beginning of the growth of the stem, leaves and flowers during the next season. A number of different kinds of bulbs such as the onion are used for food. Some other examples of the ...read more

ARTICHOKE. Artichokes are vegetables that have a very delicate flavor. There are three different kinds of artichokes: the globe, the Jerusalem, and the Chinese or Japanese. The globe and the Jerusalem artichokes are members of the Composite family like the aster, daisy, and sunflower.

The globe artichoke is also called the French or bur artichoke. A native of the Mediterranean region, today it is grown chiefly in the United States and Europe. California produces most of the United State crop, but some are grown in the southern states.

The plants are gray-green and look like this-das. They have long prickly leaves large clusters of white or lavender flowers. The plant parts that are eaten are the tender base of the flower bud (often three to four inches in diameter) and the thick, soft parts of the leaves around the bud. These parts are cut while the buds are still tightly closed.

They are sold fresh or canned, and are eaten boiled, baked, fried, stuffed, or in salads or soups.

New plants usually are grown from sprouts or shoots from older ones. Plants may live for many years, but those raised for sale usually are replanted every three or four years.

The Jerusalem artichoke may grow 12 feet tall, and ...read more

ASTER is a flowering plant of the Compositae family. It is so common in the United States that it has been suggested as the national flower. More than 175 species grow in North America. The flower also grows in parts of Europe, Asia, and South America. Toward the last of August and throughout September and October, these beautiful starry wild flowers burst into bloom. The aster (from the Greek aster, meaning “star”) was so named because of its radiating or starlike flower head. It is found largely in North America.

Asters are usually perennial plants. The flowers have yellowish or brownish disks encircled by white, purple, violet, blue, rose, or pink rays. Two handsome species are the New England aster, with its numerous large violet or purple rays, and the New York aster (Aster novi-belgii), which has light blue and white blossoms. They bloom until after the first frost. Both of these are common in the northeastern United States.

The aster is related to the daisy. It gets its name from the Greek word for star. The blossoms may be from one-half to two inches in diameter. They vary in color from white through pink, red, and blue. All have flat yellow centers surrounded by many narrow petals.

Most asters are perennial (grow ...read more

SWEET PEA. In 1699 a monk found some butterfly-shaped flowers growing wild in the fields of Sicily. He sent a handful of their seeds to a doctor in England. From the offspring of these seeds have been selected the several hundred varieties of sweet peas which are today the daintiest of garden flowers. The sweet pea belongs to the same family as the edible pea. The original flowers were purplish blue in color. Gardeners soon began to select new colors and larger flowers than were found in the wild plant. In the United States interest in sweet peas did not begin until the 1890′s. Today, however, thousands of acres in California alone are devoted entirely to growing sweet peas.

The sweet pea vine has rough, winged stems. The thin, pale green leaves bear tendrils which help to support the plant in climbing. There are two general types of sweet peas; the tall and the dwarf. The fragrant blossoms of each type vary in form from single to hooded double. In texture they vary from smooth and velvety to wavy and crinkled. The colors range from white through all the pastel tints, to blue, red, and purple.

The seeds should be sown in early spring in cool climates or in the fall in warm climates. The soil should be fairly ...read more

Sunflower is a tall plant known for its showy yellow flowers. There are more than 60 species of sunflowers. The most common type grows from 3 to 10 feet (1 to 3 meters) tall and has one or more heads of flowers. Each head consists of a disk of small, tubular flowers surrounded by a fringe of large yellow petals. A sunflower head may measure more than 1 foot (30 centimeters) in diameter and produce up to 1,000 seeds. The head turns and faces toward the sun throughout the day.

Sunflower seeds are rich in protein. They yield a high quality vegetable oil used in making margarine and cooking oil. Some varieties of sunflowers have large striped seeds, which are roasted for snack food or blended with other grains to make birdseed. Special oil-seed varieties produce small black seeds that contain up to 50 per cent oil. Sunflower oil is the world’s third most important vegetable oil. Only soybean oil and palm oil are produced in greater abundance. Sunflower oil is sometimes used as a replacement for diesel fuel.
