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

 fragrance is similar to that of the wild rose.

 introduced into a garden, and from the circumstance of its 

 having become s > fashionable of late years, I have felt

 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
