62 THE BOOK OF THE LILY 



at the base of the bulb are not sufficient to nourish the 

 plant at the critical period of growth. Therefore L. 

 auratum and others of the class should be planted 

 sufficiently deep in light soil to ensure production of 

 stem roots, but in heavy soil it is best to plant them 

 shallow, and mound soil round the bases of the stems. 



The second group is illustrated by L. Martagon, which 

 does not root freely from the stem base, therefore stem 

 roots need not be provided for. 



Most Lilies of this class are characterised by unusually 

 large and deep roots at the base of the bulb, so' that 

 they derive nourishment at a greater depth. 



Again, generally speaking (though there are excep- 

 tions), those that produce roots freely from the base of 

 the stem can be depended upon to flower well the first 

 season after planting, while the Lilies of the non-stem- 

 rooting section make but little progress towards full 

 development the first year, and need two or three 

 seasons before they attain their mature flowering growth. 

 Though there are no hard and fast lines in regard to 

 this matter, the principal Lilies may be divided with fair 

 accuracy as follows. 



Those with numerous stem roots : 



Lilium auratum. 

 ,, Brotvni. 

 , , bulbiferum. 

 , , concolor. 

 ,, croceum. 

 ,, dauricum. 

 ,, elegans. 

 Hansom. 



Lilium japonicum. 



,, Leichtlini. 



,, longiflorum. 



,, neilghcrrense. 



, , nepalense. 



,, rubellum. 



,, sulphur eum. 



,, tigrinum. 



,, Henry i. 



Those with few, if any, stem roots : 



Lilium canadense. 

 candidum. 



Lilium carniolicum. 



halcedonicum.
