BIENMAL AND TERENNIAL FLOWERS. 31 



The reader is here reminded that our catalogue of 

 Annual flower seeds, contains a few varieties of Perennials, 

 which were there introduced because of their aptness to 

 blossom in the first season from the sowing of seeds ; these 

 with those marked f in the last catalogue, may he sown 

 and treated in the manner recommended for the tender 

 Annuals. Those intended to be cultivated as greenhouse 

 plants, should be taken up before the approach of cold 

 weather, transplanted into flower pots, and sheltered either 

 in -a garden frame, greenhouse, or light room. Those 

 plants with tuberous roots, such as Dahlias, Marvel of Peru, 

 and also some others of the Bean and Pea tribe, may be 

 cut down late in the Autumn ; the roots may be then taken 

 up and preserved in the same manner as those of other 

 tuberous and bulbous-rooted plants, of which I shall treat 

 hereafter. 



Hardy Biennial and Perennial flower seeds may be sown 

 in the month of April, in shallow drills. If this business be 

 performed in the manner recommended for Annuals, they 

 can be easily distinguished from each other ; and as these 

 plants do not flower the first year, they may be thinned out, 

 or removed from the seed beds as soon as they are well 

 rooted, and planted either into different parts of the flower 

 beds, or in a nursery bed. Ifthe latter plan be adopted, 

 they should be planted in rows a foot or more apart, and 

 kept free from weeds by mpans of a small hoe, which will 

 greatly promote their growth, and prepare them for trans- 

 planting into the regular and permanent blossoming beds, 

 either in ihe Autumn or early in the ensuing Spring. 



It may be here observed that Biennials seldom survive the 

 second Winter to flower in perfection, unless they are renewed 

 by cuttingsoftop shoots, youngflower stalks, or casual offsets, 

 layers, &c. It will be unnecessary to take this trouble, 

 unless it be with any extraordinary double-flowering plants. 

 Some of the Perennials may be increased by root offsets 

 detached from the old plants, and planted in Spring or
