BIENNIAL A3JD PERENNIAL FLOWERS. lf 



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 trans- 

 planting into the regular and permanent blossoming beds, 

 either in the Autumn or early in the ensuing Spring. 



It may be here observed that Biennials seldom servive the 

 second Winter to flower in perfection, unless they are renewed 

 by cuttings of top shoots, young flower 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 

 Autumn ; others by bottom suckers and slips of top shoots, 

 layers, pipings of young shoots, <fcc. Pinks, Sweet Williams 

 Pansies and double Violets, also Periwinkle, or running 

 Myrtle, and many other similar plants, may be increased 

 by simply laying their branches an inch or two under the 

 surface in July and August.. After roots have formed, 

 which may be expected in six or eight weeks, each tuft or 

 plant may be transplanted into the borders. 



Many sorts of Biennial and Perennial flower seeds may 

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

 plants get strong Lefore the setting in of Winter, some of 

 them will flower the Summer next ensuing. The following 

 are amongst the hardiest : 



Adonis, Spring -flowering. Lychnis, in varieties 



Alpine Columbine. Larkspur, perennial.

It may be necessary here to remind the reader of those 

 species of beautiful double-flowering Perennial herba- 

 ceous plants, which do not produce seed ; some of these 

 are included in our Catalogue, they may be obtained at the 

 nurseries, and should be introduced into the regular flower
