Amaryllis.—The popular name of a variety of house or conservatory tender bulbs, but properly applied only to the Belladonna lily. Most of them are hippeastrums, but the culture of all is similar. They are satisfactory house plants for spring and summer bloom. One difficulty with their culture is the habit of the flower-stalk starting into growth before the leaves grow. This is caused in most cases by stimulating root growth before the bulb has had sufficient rest.
The bulbs should be dormant four or five months in a dry place with a temperature of about 50°. When wanted to be brought into flower, the bulbs, if to be repotted, should have all the dirt shaken off and potted in soil composed of fibrous loam and leafmold, to which should be added a little sand. If the loam is heavy, place the pot in a warm situation; a spent hotbed is a good place. Water as needed, and as the flowers develop liquid manure may be given. If large clumps are well established in 8-or 10-inch pots, they may be top-dressed with new soil containing rotted manure, and as growth increases liquid manure may be given twice a week until the flowers open. After flowering, gradually withhold water until the leaves die, or plunge the pots in the open, in a sunny place. The most popular species for window-gardens is A. Johnsoni (properly a hippeastrum), with red flowers. Figs. 257, 261.
Bulbs received from dealers should be placed in pots not much broader than the bulb, and the neck of the bulb should not be covered. Keep rather dry until active growth begins. The ripened bulbs, in fall, may be stored as potatoes, and then brought out in spring as rapidly as any of them show signs of growth.
Anemone.—The wind-flowers are hardy perennials, of easy culture, one group (the Anemone coronaria, fulgens, and hortensis forms) being treated as bulbs. These tuberous-rooted plants should be planted late in September or early in October, in a well-enriched sheltered border, setting the tubers 3 in. deep and 4-6 in. apart. The surface of the border should be mulched with leaves or strawy manure through the severe winter weather, uncovering the soil in March. The flowers will appear in April or May, and in June or July the tubers should be taken up and placed in dry sand until the following fall. These plants are not as well known as they should be. The range of color is very wide. The flowers are often 2 in. across, and are lasting. The tubers may be planted in pots, bringing them into the conservatory or house at intervals through the winter, where they make an excellent showing when in bloom.
The Japanese anemone is a wholly different plant from the above. There are white-flowered and red-flowered varieties. The best known is A. Japonica var. alba, or Honorine Jobert. This species blooms from August to November, and is at that season the finest of border plants. The pure white flowers, with lemon-colored stamens, are held well up on stalks 2-3 ft. high. The flower-stems are long and excellent for cutting. This species may be propagated by division of the plants or by seed. The former method should be employed in the spring; the latter, as soon as the seeds are ripe in the fall. Sow the seed in boxes in a warm, sheltered situation in the border or under glass. The seed should be covered lightly with soil containing a quantity of sand and not allowed to become dry. A well-enriched, sheltered position in a border should be given.
The little wild wind-flowers are easily colonized in a hardy border.
Aralia, A. Sieboldii (properly Fatsia Japonica and F. papyrifera), as it is sometimes called, and the variety variegata, with large, palmlike leaves, are grown for their tropical appearance.
Sow in February, in shallow trays and light soil, in a temperature of 65°. Continue the temperature. When two or three leaves have formed, transplant into other trays 1 in. apart. Sprinkle them with a fine rose or spray; and do not allow them to suffer for water. Later transfer them to small pots and repot them as they grow. Plant out in beds after the weather has become warm and settled. Half-hardy perennials in the North, becoming 3 ft. or more high; a shrub in the South and in California. Used often in subtropical work.
Araucaria, or Norfolk Island pine, is now sold in pots by florists as a window plant. There are several species. The greenhouse specimens are the juvenile state of plants that become large trees in their native regions; therefore, it is not to be expected that they will keep shapely and within bounds indefinitely.
The common species (A. excelsa) makes a symmetrical evergreen subject. It keeps well in a cool window, or on the veranda in the summer. Protect it from direct sunlight, and give plenty of room. If the plant begins to fail, return it to the florist for recuperation, or procure a new plant.
