PURPLE PENTSTEMON 



Pentstemon lyallii Gray 



Purple pentstemon is one of the finest of all the pentstemons, 

 •especially when it finds a congenial situation. In disintegrated lime- 

 stone it thrives luxuriantly, often forming low dense clumps two or 

 three feet in diameter and completely covered with large purple 

 blossoms which resemble those of foxglove, one of its relatives. The 

 flowers, borne at the ends of the stems, are so heavy that they weigh 

 the branches to the ground. On slopes above timberline where it is 

 subjected to severe climatic conditions it is very beautiful in contrast 

 with gray rocks, especially when growing in rock crevices. 



Purple pentstemon belongs to the Figwort Family and ranges 

 from Idaho and Montana northward to Alberta and British Columbia. 



We gathered them in perfection in Sinclair Canyon, near Radium 

 Hot Springs, British Columbia, at an altitude of 3,000 feet.
