Shrubs







The shrubs of dwarf habit available for growing inside in winter are numerous and valuable. They include a number of the most attractive plants one may have, and as a rule will stand more hardships in the way of poor light, low temperature and irregular attention than any of the other flowering plants. They differ from the other flowering plants in several ways. They are harder wooded; the resting spell is more marked and they make growth and store up energy for flowering ahead of the blossoming season. Their differences in habit of growth naturally involve differences in treatment. In the first place, they are harder to propagate; in many cases it is better for the amateur to get plants from the florist than to try to raise them. This is not such a disadvantage as might at first appear, because most of them can be kept for several years, only improving with age. The "snapping" test (page 30) will not apply to many of the shrubs when taking cuttings. In this case they are made from the new growth after it becomes firm and well ripened. It should be fresh and plump, and rooting will be made more certain by bottom heat. Often cuttings of hard-wooded plants, such as oleander, are rooted in plain water, in wide-mouthed bottles hung in a warm place in the sun, the water being frequently renewed or kept fresh with a lump or so of charcoal. Many of the shrubs are beautiful for summer blooming on the veranda or in large pots or tubs. These may be kept over winter safely by drying off and keeping in a frost-proof cellar where they will get little light. In this way they will come out again in the spring, just as hardy shrubs do out-of-doors. The earth should not be allowed to get dust dry, but should not be more than slightly moist; very little, and often no, water is required, especially if mulching of some sort is put over the earth in pots or boxes; but it should not be any material that would harbor rats or mice. The leaves will fall off, but this is not a danger signal, such plants being deciduous in their natural climates. It will be best to keep such plants as are to be stored in the cellar, from the time there is danger of frost until about November first, in an outbuilding or shed, where they will not freeze. This makes the change more gradual and natural. The temperature of the cellar should be as near thirty-four to thirty-eight degrees as possible. About March first will be time to start giving most plants so treated heat, light and water again, the latter gradually. The fact that growth is made in advance of the flowering period means that the summer care and feeding of such plants is very important. Plenty of water must be given, and frequent applications of liquid manure or fertilizers, or top dressing. Flowering shrubs that bloom on last season's wood, like hydrangeas, should be pruned just after blooming. Abutilon--The Flowering Maple (Abutilon) is an old favorite, but well worthy of continued popularity. It is practically ever-blooming, which at once marks it as highly desirable. The pendulous flowers are very pretty, coming in shades of pink, white, yellow and dark red. The foliage is also beautiful, especially that of the variegated varieties, than which very few plants are more worthy of a place in the window gardener's collection. New plants, which will grow and bloom very rapidly, are propagated by cuttings rooted in the fall or spring. Give the plants when indoors plenty of light. Old plants, for which there is not room in the window garden, may be wintered almost dry in a cool place and allowing the leaves to fall off. The varieties are numerous. Some of the best are Santana, deep red; Boule de Neige, pure white; Gold Bell, yellow; Darwini tesselatum; Souvenir de Bonn and Savitzii (the latter the most popular of all variegated); Eclipse and vexillarium, trailing in habit. Acalypha--Valuable for its variegated foliage. For use in the house root cuttings in early fall. The old roots, after cutting back, may be kept on the dry side to furnish cuttings in spring for the garden plants. Aralia--Aralia (Fatsia Japonica) and A. J. variegata, especially the last, are two of the most decorative plants one may have. They are not widely known--very likely because they are difficult to propagate. Easily kept. Get from florist. Ardisia--(Ardisia crenulata) is the best red berried plant for the house. It is a dwarf, with very beautiful dark green foliage. While kept healthy it will be laden constantly with its attractive clusters of berries, one crop lasting over the next. Seedlings make the best plants, and are readily grown. Sow in January to April, and plants will flower within a year and thereafter be perpetually decorated. Old plants can be topped (see page 86) and make fine specimens. By all means give the ardisia a place in your collection. Aucuba--The Gold Dust Plant: one of the beautiful shrubs and especially valuable for decoration because doing well in such shaded positions as inner rooms, or by doorways. Strong tip cuttings--six to ten inches--can be rooted readily in the fall. Give a soil on the heavy side. Azalea--The azalea is the most beautiful flowering shrub--if not the most beautiful of all winter flowering plants. With proper treatment an azalea should do service for several years, becoming more splendid each season. You will probably get your plant when it is in full bloom. At this time, and during the whole growing season, it requires abundant water. The best way to make sure of giving it a thorough one, is to stand it for half an hour in a pail of water. Keep it in a rather cool place, say forty-five at night, and the flowering season, which should last several weeks, will be prolonged. With the azaleas you must do the work for next year's success as soon as the flowering season is over. After repotting, keep in a temperature of fifty to fifty-five degrees at night. There are three types of azalea suitable for winter blooming, the Indian, Ghent and Mollis, of each of which there are several kinds. The Indian type has the advantage of not blooming without its leaves, as the others do. The best way to select the varieties wanted is to purchase when in bloom. It will not pay the amateur to attempt propagation. Bouvardia--Pink, white or red flowers, sweet scented. Propagated by root cuttings, but as the plants are good for a number of years, the best way is to get them from the florist. Old plants may be divided, small enough to go into number three pots. Give either cuttings or divisions about sixty degrees at night after potting, which should be in spring, until put outdoors. Keep pinched to shape. Then bloom from late fall to February. Browallia--A very attractive flowering shrub, easily grown in a cool room, with plenty of sunlight. Sow seeds in 4-inch pots in August, thinning to three or four. Repot to 6 inches. Cuttings make good plants. Best grown as standards. B. elata is especially valuable because of its deep blue flowers. B. Jamesonii is orange. Roezlii and Grandiflora, blue or white. Daphne--D. odora is easily grown and very fragrant. As ornamental as orange or lemon and very free flowering. Give almost no water in winter, or store in cellar. Plants good for many years. Genista--A beautiful evergreen shrub, bearing freely in spring clusters of pea-shaped yellow flowers, richly fragrant. Cut back after flowering, and in fall put in a cold room, forty degrees, or a frame, giving several weeks rest. Cuttings may be rooted readily in spring, when pruning the plants. Grevillea robusta--The Silk Oak is grown with the greatest ease and makes an extremely graceful, beautiful plant, either by itself or as a center for fern dishes, etc. Sow in March and grow on with frequent shifts. Hibiscus--One of the most brilliant flowering shrubs outside of the azaleas, with single and double flowers. Give a warm, sunny spot. Large plants can be stored in the cellar. Cuttings in spring or summer will furnish new plants. Hydrangea--This is another popular flowering shrub, often had in bloom inside in the spring, but personally I do not consider it suited for such use. The flowers are rather coarse to bear close inspection, such as a house plant must be subject to: they are far more effective in masses out-of-doors or used as semi-formal decorations about paths or stoops, for which purpose they are unsurpassed. If you care to have them bloom indoors, get small plants from the florist, or start cuttings of new growth in spring, taking shoots which do not have buds. After flowering, cut back each branch and grow on, in a cool airy place with slight protection from noonday sun. Take into the house before frost, and gradually dry off for a rest of six weeks or more in a cold room. Then start into growth. Plants for flowering early in the spring outdoors should be treated in the same way during summer, and wintered in the cellar, as directed above. Take up to the light any time after first of March in the spring, but be careful to harden off before setting outside. The varieties of the hydrangea are several, some being entirely hardy farther north than New York, but the sorts best for house and tub culture are not. Most of them will come through some winters, but it doesn't pay to take the chance. H. Hortensia Japonica is the blue flowering variety; the color will depend much, however, upon the soil. To make sure of the color, dissolve one pound of alum in two quarts of ammonia, dilute with twenty gallons water and use as a liquid fertilizer. Thomas Hogg is a beautiful pure white, quite hardy. H. h. Otaksa, pink, is one of the most popular. Lantana--Easily grown flowering shrub, trailing in habit, with small flower clusters of white, pink, red, yellow or orange. New dwarf varieties best for pot culture. Cuttings root easily. I have never cared for this plant, and its odor is not pleasant to most people. Lemon--The best lemon for house culture is the Ponderosa, or American Wonder, of comparatively recent introduction. Most florists now have it. Easily grown and a very attractive plant. The fruit is good to use. Lemon Verbena (Aloysia citriodora)--Many people consider this the most delightfully fragrant plant grown. Certainly no window garden should be without it. Early in September cut back old plants, if in the garden, and pot up. New growth will quickly be made. Plants kept in pots should be rested in early winter by keeping dry and cool. Spring cuttings root easily. Oleander--A beautiful old-time favorite, with fragrant blossoms of red, pink, yellow or white. Give a very rich soil and plenty of water when growing. Rest after flowering. Cuttings are rather hard, but will root with care. Orange--There are several sorts suited to house culture, and they should be more frequently tried, as a well grown plant will have flowers, green fruit and attractive golden oranges almost all the time--to say nothing of its foliage beauty and delightful fragrance. Their rest period should be given during November, December and January. Otaheite Orange is the one most commonly grown for house culture, and while the fruit is of no use for eating, it has the more valuable advantage of remaining on the tree (which is eighteen to twenty-four inches high) for months. Satsuma is another good sort. Kumquat (Citrus Japonica) is also very attractive. Reinwardtia (known usually as Linum trigynum)--Another attractive flowering shrub, with light or bright yellow flowers. Cuttings will root with bottom heat in April. L. tetragynum is a companion variety. Roses--Those who will take the proper pains can grow roses successfully in the house; but as a general rule satisfactory results are not obtained. The first essential to success is the use of the right varieties and those only. The second is a moist atmosphere; the third is cleanliness,--insect enemies must be kept off. For soils, growing in summer, etc., see Part II, page 188. The best varieties for house culture are the Crimson Baby Rambler (Mme. Norbert Levavasseur), Pink Baby Rambler (Anchen Muller), Crimson Rambler, Clothilde Soupert, Agrippina, Hermosa, Safrano, Maman Cochet, White Maman Cochet and La France. If the plants are set in a window-box (see page 9) about one foot apart, they will be more easily cared for than in pots. They may be treated in two ways. (1) After blooming, cut away most of the old growth and enforce rest during the summer. Start again in October and grow on in the house. (2) Grow on through the summer and dry off in the fall as the leaves drop. Store in a cold place (a little freezing will not hurt) until about January first. Then prune back severely--about half--and bring into warmth and water. A combination of the two methods will give a long flowering season. Swainsona--A shrub of vine-like habit, bearing flowers, white and light pink, which greatly resemble sweet peas. The foliage is unusual and very pretty. It should be trained up to stakes or other supports and cut back quite severely after flowering. Sweet Olive (Olea fragrans)--This is still another fragrant flowering shrub and one of the very easiest to grow. The house shrubs, having harder stems and tougher leaves than other classes of plants, will stand many hardships that to the latter would prove fatal. They are, however, particularly susceptible to attacks of red spider and scale. Keep your shrubs clean. If you do not, in spite of their seeming immunity to harm, you will have no success with them. Syringing, showering, washing, spraying with insecticides, even giving a next-to-freezing rest,--all the remedies mentioned in Chapter XVII on Insects and Diseases--may at times have to be resorted to. But, at whatever trouble, if you want them at all, keep your shrubs clean.
