70 DOUBLE DAHLIA 



Persicum, will bloom in a greenhouse, or warm room, from 

 January to April, if planted in a good light compost early 

 ia September. The foliage of these plants is of a dark 

 green velvet colour; and the flowers of the variety Coum 

 are of a dark crimson colour ; those of the variety Persicum 

 are of a delicate French white, tipped with pink, and their 

 fragrance is similar to that of the wild rose. 



DOUBLE DAHLIA. 



This may with propriety be denominated one of the moss 

 important perennial tuberous-rooted plants that can be 

 introduced into a garden, and from the circumstance of its 

 having become so fashionable of late years, I have felt 

 anxious to furnish in this work, a catalogue of all the 

 choicest varieties attainable ; I therefore applied to Mr. G. 

 C. Thorburn, who, from a regular correspondence with con- 

 noisseurs, both in England and America,becomes acquainted 

 with all the most beautiful and rare varieties. He has 

 kindly furnished a list and description of about one hun- 

 dred; including the choicest seedling's of 183S and 1839, 

 which will be cultivated for the first time in America, in his 

 garden at Astoria, 1840 ; plants from which will be for sale a^ 

 No. 11 John street. To these I have added about two hun- 

 dred and fifty varieties, most of which I have had under 

 cultivation in my own garden, and which may be justly 

 denominated pre -eminent. 



In making this selection, several superb varieties are 

 omitted, not because they are undervalued, but for the sake 

 of brevity, which in a work of this kind must be consulted. 

 Those marked thus f are native American varieties. Those 

 marked thus * obtained the greatest number of premiums 

 at the various Floricultural and Horticultural exhibition* in 

 Great Britain, as well as in our own country. There are, 

 perhaps, a hundred more in this catalogue not far beneath
