CATALOGUE OF GREENHOUSE PLANTS. 107 



sufficiently capacious to hold them without crowding them, 

 as this will cause the plants to grow weak and slender. If 

 such happens early in the Summer, a stocky growth may be 

 produced by clipping the tops, and they will bloom in great 

 perfection in their usual season. 



INTRODUCTION TO THE 



CATALOGUE OF GREENHOUSE PLANTS. 



To promote brevity and avoid tautology, I here submit the 

 following statement : — 



That the directions accompanying our catalogue of An- 

 nual, Biennial and Perennial Flower Seeds, will apply to 

 such plants in the green-house department as are ordinarily 

 raised from seed. 



That the directions annexed to the catalogue of Flower- 

 ing and Ornamental Shrubs, for propagation by cuttings, 

 layers, &c, are applicable to a great proportion of the 

 plants hereinafter described, and that the exceptions are 

 shown in the monthly calendar. 



That such Bulbous roots as are generally embraced in 

 Greenhouse Catalogues, from their being adapted to artifi- 

 cial culture, have been already treated of, under each head, 

 in numerous articles; to which the reader is referred. 



That with the exception of Hot-house plants, which re. 

 quire a uniformly warm climate to perpetuate their exis- 

 tence, all such other tender and half hardy plants as need 

 protection in Winter, may come under the denomination of 

 Greenhouse Plants ; some species however, notwithstanding 

 this concession, may be preserved in frames, pits, cellars, or 

 warm rooms. 



That many of those species designated thus, § and 

 thus f in our two first catalogues, are of such description ; 

 and as they have been treated of in the chapters thereto an- 

 nexed, the following catalogue and explication will be 

 necessarily brief, when compared with one general catalogue 

 of exotic plants.
