22 BIENNIAL AND PERENNIAL FLOWER SEEDS. 



Biennial and perennial flower seeds may be sown in 

 the month of April, in shallow drills. It 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 differ- 

 ent parts of the flower beds, or in a nursery bed. if 

 the latter plan be adopted, they should be planted in 

 rows a foot or more apart, and kept free from weeds 

 by means of a small hoe, which will greatly promote 

 their growth, and prepare them for transplanting into 

 the ground, (where they are intended to flower,) 

 either in the autumn or early in the ensuing spring. 

 It may be remarked that biennials are raised principally 

 from seed sown every year. They seldom • urvive 

 the second winter to flower in perfection, unless they 

 are renewed by cutting of top shoots, young flower 

 stalks, or casual root- 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 Autumn ; 

 others by bottom suckers and slips of top shoots, lay- 

 ers, and pipings of young shoots, &c. 



Many sorts of biennial and perennial flower seed* 

 may be sown in September, or as soon as ripe ; and if 

 the plants get strong before the setting in of winter, 

 some of them will flower the summer next ensuing.
