used. Others are L. parvum, from the sub-alpine regions, 

 with many small bell-shaped flowers, orange in the middle, 

 with crimson tips ; L. columbianum, native of British

 with maroon, in July. 



All these bog Lilies grow naturally along the banks 

 of small streams, on the borders of lakes in alpine

 leaf-soil or humus. Low shrubs and other plants shade 

 the ground and keep the bulbs from getting dry, and 

 through them the stems push their way and open their 

 flowers to the sun. Other Lilies that may be used are the 

 charming little L. concolor, from China and Japan, only 

 a foot or two high, with bright scarlet flowers in June. 

 L. chalcedonicum, from Greece, with the same coloured 

 flowers in July, but taller in habit ; L. pyrenaicum, a free 

 growing and bushy plant, from the Pyrenees, bearing, in 

 May, bright yellow, spotted flowers having a very strong

 Siberia, only eighteen inches high, with narrow leaves, 

 and bright scarlet flowers in July. These all like a deep 

 loamy soil rich in humus, with plenty of moisture when 

 growing. Low bushes are also an advantage to shade

 spring,
