 native of British Columbia. It grows 4^ feet high and from 

 early in June to early in July it is a mass of large, plume-like 

 panicles of creamv white flowers. 



Among lilies, what is more effecti\'e than our native Lilmm

Of hardv native orchids of great beauty which do well under 

 cultivation with special preparation of soil and partial shade, 

 may be mentioned Cypripedium spectahile, Cypripedhim puhescens,
