A beautiful hardy perennial, with evergreen leaves, 

 and decumbent, rooting stems, by which it is readily in- 

 creased. Native of open grounds and banks of streams 

 in the districts around the mouth of the Columbia River, 

 where it was found abundantly by Mr. Douglas. Our 

 drawing was made at the Garden of the Horticultural 

 Society in 1827. 



Grows freely either in common light garden soil or in 

 Ihe American borders, in both which situations it flowers 

 in the utmost profusion from June till its growth is 

 arrested by frost. 



Root perennial, creeping. Stems decumbent, root- 

 ing, branched, U to 2 feet high, round, smoothish, 

 purple. Leaves evergreen, ovate-oblong, unequally ser- 

 rated, smooth, deep green; the upper serrated, the lower 

 decurrent on the petiole. Peduncles axillary, pubescent.
