Petunias
Probably no common flower of the garden has been so improved during the last few years as the Petunia. The small-flowered variety of a few years ago with its straggly habit and narrow range of colour—chiefly white and faded magenta—is now superseded by magnificently fringed and ruffled beauties in a wealth of colour, from purest white to glowing crimson, and a velvety purple that is almost black, with wonderfully veined and tinted throats and thick, stocky stems. It is difficult to realise that they are the same plants, plus a few generations of good living and culture.
The double Petunias are desirable for pots, vases, and bedding out, but I do not think they compare with such strains as Burpee’s Defiance, the Giants of California, the Ruffled Giants, and the Miranda. Miranda, for example, is a rosy carmine merging into a brilliant scarlet in the throat—the nearest approach to a scarlet Petunia yet produced. The seed of double Petunias will yield a fair proportion of double flowers. The young plants of both the single and double varieties require great care at first, being very sensitive to hot sun or cold air. Once established, however, they will stand a great deal of both—more, indeed, than almost any other flower of this class. Plant them in flats in the house in March by pressing the seed into the soil without covering; keeping moist and warm until the seed germinates, usually from eight to ten days. When large enough to handle, prick off into larger flats and set them in a warm north or east window. When the leaves touch set them two or three inches apart each way in other flats and let them grow until it is time to place them in the open ground, hardening them gradually by exposure to more sun and air each day, and transplant with great care. If intended to replace the Pansies they may be set in the bed in June, the Pansies affording them protection until they have attained some size. Set each little seedling on the north-east side of a Pansy plant, and by the time the Pansies have passed their zenith they will be ready to stand alone.
Always remove poor or inferior plants in order that the highest standard may be maintained; the finer varieties may be readily distinguished from the more common sorts by the stems and foliage; the latter having thin stems and small leaves, set rather far apart, while the stems of the fine varieties are very stocky; the leaves large, more or less crinkly, and set closely on the stem; the buds thick and compact, while those of the common type are long and thin. Petunias grow so rapidly that vacant places left by culling are soon filled. The finest specimens may be lifted for winter flowering. They will bloom freely in the house and often show a richer colour than when out of doors. They need considerable root room—any crowding of the roots, or starving of the plants being quickly shown in the deterioration of the flowers. Avoid chills and draughts. Give liquid manure and water freely, but do not let the soil get wet or sour. A little charcoal in the potting soil is an excellent corrective of this tendency. Always remove the flowers as they fade, thus prolonging the blooming season and increasing the beauty and size of the blossom.
