Petunias. - No class of summer flowers better repay the small care they require, than Petunias; they are a mass of gay bloom from June to November, and, when planted in patches, or in beds, or even in pots, or vases, flower ad infinitum. They are successfully raised from seed, sown in a hot-bed in March; they may afterwards be pricked out into small pots, and, when sufficiently strong, turned into the open ground, some time in May. A' bed of good seedlings, in full bloom, is a brilliant sight.

The finer varieties are increased from cuttings. The best time is late in the summer, and from plants that have been headed down for that purpose; or, if the plants are taken up in autumn, and kept in the green-house, they will make abundant increase from cuttings during the winter. As it is not generally convenient to keep the plant over the winter, it is more economical to purchase a new stock of choice varieties of the florist every spring, as the best sorts are sold at about $2 per dozen.
