FLOWER-GARDENING. 99 



That the directions accompanying our Catalogue of Annual, 

 Biennial, and Perennial Flower Seed, will apply to such plants 

 in the green-house department as are ordinarily raised from 

 seed. 



The directions annexed to the Catalogue of Flowering and 

 Ornamental Shrubs, including propagation by cuttings, layers, 

 etc., are applicable to a great portion of the plants hereinafter 

 described ; and also to such Bulbous roots as are generally 

 embraced in green-house catalogues, from their being adapted 

 to artificial culture, having been already treated of, under each 

 head, in numerous articles ; to which the reader is referred. 



With the exception of hot-house plants, which require a 

 uniformly warm climate to perpetuate their existence, all such 

 other tender and half-hardy plants as need protection in winter, 

 may come under the denomination of green-house plants ; some 

 species, however, may be preserved in frames, pits, cellars, or 

 warm rooms. Many of those species designated thus and 

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

 as they have been treated of in the chapters thereto annexed, 

 the following catalogue and explication will be necessarily brief, 

 when compared with one general catalogue of exotic plants. 



DESCRIPTIVE CATALOGUE. 



Acacia. Of this and the Mimosa, which are by some con 

 sidered as one genus, there are upwards of a hundred species 

 and varieties, suited for artificial culture. The blossoms, which 

 are generally straw-color and yellow, except the most tender, 

 some of which are crimson, succeed each other from February 

 to June. 



Agapanthus. A beautiful species of Lily, producing large 

 blue flowers from April to June ; some varieties have striped 

 leaves and delicate white blossoms.
