It may be repeated here that a person cannot expect to grow a plant satisfactorily until he learns the natural time of the plant to grow and to bloom. Many persons handle their begonias, cacti, and azaleas as if they should be active the whole year round. The key to the situation is water: at what part of the year to withhold and at what part to apply is one of the very first things to learn.
Abutilons, or flowering maples as they are often called, make good house plants and bedding plants. Nearly all house gardeners have at least one plant.
Common abutilons may be grown from seed or from cuttings of young wood. If the former, the seed should be sown in February or March in a temperature of not less than 60°. The seedlings should be potted when about four to six leaves have grown, in a rich sandy soil. Frequent pottings should be made to insure a rapid growth, making plants large enough to flower by fall. Or the seedlings may be planted out in the border when danger of frost is over, and taken up in the fall before frost; these plants will bloom all winter. About one half of the newer growth should be cut off when they are taken up, as they are very liable to spindle up when grown in the house. When grown from cuttings, young wood should be used, which, after being well rooted, may be treated in the same way as the seedlings.
The varieties with variegated leaves have been improved until the foliage effects are equal to the flowers of some varieties; and these are a great addition to the conservatory or window garden. The staple spotted-leaved type is A. Thompsoni. A compact form, now much used for bedding and other outdoor work, is Savitzii, which is a horticultural variety, not a distinct species. The old-fashioned green-leaved A. striatum, from which A. Thompsoni has probably sprung, is one of the best. A. megapotamicum or vexillarium is a trailing or drooping red-and-yellow-flowered species that is excellent for baskets, although not now much seen. It propagates readily from seed. There is a form with spotted leaves.
Abutilons are most satisfactory for house plants when they are not much more than a year old. They need no special treatment.
Agapanthus, or African lily (Agapanthus umbellatus and several varieties).—A tuberous-rooted, well-known conservatory or window plant, blooming in summer. Excellent for porch and yard decoration.
It lends itself to many conditions and proves satisfactory a large part of the year, the leaves forming a green arch over the pot, covering it entirely in a well-grown specimen. The flowers are borne in a large cluster on stems growing 2-3 ft. high, as many as two or three hundred bright blue flowers often forming on a single plant. A large, well-grown plant throws up a number of flower-stalks through the early season.
The one essential to free growth is an abundance of water and an occasional application of manure water. Propagation is effected by division of the offsets, which may be broken from the main plant in early spring. After flowering, gradually lessen the quantity of water until they are placed in winter quarters, which should be a position free from frost and moderately dry. The agapanthus, being a heavy feeder, should be grown in strong loam to which is added well-rotted manure and a little sand. When dormant, the roots will withstand a little frost.
Alstremeria.—The alstremerias (of several species) belong to the amaryllis family, being tuberous-rooted plants, having leafy stems terminating in a cluster of ten to fifty small lily-shaped flowers of rich colors in summer.
Most of the alstremerias should be given pot culture, as they are easily grown and are not hardy in the open in the North. The culture is nearly that of the amaryllis,—a good, fibrous loam with a little sand, potting the tubers in early spring or late fall. Start the plants slowly, giving only enough water to cause root growth; but after growth has become established, a quantity of water may be given. After flowering they may be treated as are amaryllis or agapanthus. The roots may be divided, and the old and weak parts shaken out. The plants grow 1-3 ft. high. The flowers often have odd colors.
