A genus of hardy, free-flowering plants belonging to the So-lanum family, natives of Brazil and the Argentine Republic. They are very showy and effective for planting in beds or masses, also for planting in waste ground or where water is not very plentiful. They thrive in any soil and require very little attention in the way of watering if the soil about the plants is kept loose and clear of weeds. If extra large flowers are wanted, give them good rich soil and a reasonable amount of water.
Petunias are raised principally from seeds sown in February, one-sixteenth of an inch deep, in a cold frame, pricked off (into boxes) three inches apart, and, as soon as they are of sufficient size, hardened by being placed in the open air for a week or ten days and then planted where they are to flower.
Special varieties, such as the double and finely-fringed single, are propagated by cuttings; these should be taken off in September and inserted in sandy soil, either in boxes or in the bed of the trame, and kept shaded during the middle of the day until young roots begin to form, when they should be given more air and light and gradually exposed to full sunshine. Plant them out of doors, where they are to bloom, at any season where there is no frost, and in other sections as soon as cold weather is past in the Spring.
