 Slipper, which grows about eight inches high, blooms 

 late in spring, and produces white flowers marked 

 with purple. It is a Siberian plant. It likes a shady 

 place. Macranthum is a splendid species, growing 

 a foot high and producing rosy purple flowers in 

 summer. It thrives in coarse loam and leaf mould. 

 Spectabile is about the finest of all. It grows about 

 two feet high and bears rose and white flowers of great 

 beauty in summer. It is a North American plant, 

 thriving in coarse loam, leaf mould and peat. There 

 is a white variety of it called album. Other species

 collection are acaule, with rosy-purple, fragrant flowers
