are required it will be better to procure them from some 

 florist. The following is a list of hardy Biennials Canter- 

 bury Bells, two and a half feet high ; Foxgloves, three to 

 four feet, suitable for shady places ; Sweet Rocket, one 

 foot; Sweet William, one foot; Wallflowers, two feet; 

 purple and scarlet Brompton Stocks ; the Scarlet Brompton 

 and Queen Stocks, and the intermediate resemble the habit 

 of the Brompton. Double Stocks may be perpetuated by 

 making cuttings of well-ripened shoots which sometimes 

 appear after they have flowered. Treat the cuttings as 

 directed for geraniums, &c. 



Perennials (or Herbaceous Plants). Perennials 

 are sown in one year and flower in the next ; but although 

 they die down in Winter, the roots remain alive and the 

 plants spring up every year. This section of plant life 

 embraces by far the largest number of plants cultivated in 

 our gardens. They may be propagated either by seeds, 

 cuttings, or by division of the roots. The seed may be 

 sown any time from ist October till the end of November, 

 and transplanted, when fit, as directed for biennials. 



Propagation. Such plants as the Phloxes, Penstemons, 

 Campanulas, Delphiniums, &c., may be propagated in 

 December by cuttings, if desired, planted in a cool, shady 

 border ; or they may be lifted either after they have done 

 blooming, and the leaves have withered, or early in Spring, 

 and divided into as many plants as the tuft will permit of, 

 taking care to have a good bundle of fibrous roots to each 

 piece. Paeonies, Salvias, Dielytra spectabilis, and a host of 

 other plants may be increased in this manner. Where 

 perennials are extensively used for border decoration, they 

 should be planted with a view to furnishing flowers the 

 whole of the season. This may be done in the following 

 manner : put in one that flowers in Spring, then one that 

 flowers in Autumn, then one that flowers in Summer, then 

 an Autumn one, next one of the Spring flowering, and then 

 one of Summer flowering. Mix the colours in the same 

 manner. By this means the general effect will be good, and 

 no part of the border will be at any time without bloom. 

 The following are a few of the most suitable (in addition to 

 those already mentioned) for general cultivation.
