Hydrastis is easily cultivated. Any good garden soil into which leaf mould has 

 been well worked, and a shady situation will answer its requirements. It has been 

 successfully grown on a small scale in the shade of a row of shrubs and trees in our 

 Botanic Garden. When it is grown for commercial purposes it is better to give it 

 artificial shade by a framework of lath such as is used in the cultivation of Ginseng. 



Golden Seal is sometimes confused with Gold Thread (Coptis trifolia (L.) 

 Salisb.), another perennial of the woods belonging to the same family. But, as the 

 rootstock of Golden Seal is short, thick and knotted and that of the Gold Thread is 

 long, slender and smooth, they are easily distinguished by these points alone, apart 

 from other, dissimilarities of growth. (See illustration Plate XXI, Bigs. 2 and 3). 

 The rootstock of Gold Thread extends horizontally near the surface of the soil thus 

 making its deep, yellow colour conspicuous. Although Gold Thread is very bitter, it 

 is not unpleasant and has no odour, while Golden Seal has a distinctly disagreeable 

 cdour and an unpleasantly bitter taste. 



Seed Collection and Herbarium. 



The seed collection and the herbarium have been added to from time to time as 

 opportunity permitted. About 500 specimen sheets were added during the year. 

 Specimens of the Painted Trillium (Trillium undulatum Willd.) were brought from 

 Prince Edward Island, which is a new locality for this rather rare species. 



Several different kinds of seeds and plants of particular interest in the seed 

 collection and greenhouse were brought from Bermuda.
