42 LILIES 



3epth of soil above the top of the bulb should 

 be from three to seven inches. The normal 

 size of the bulb some are quite small and the 

 vigor of the species are determining factors. 

 But there is a -third highly important point to 

 bear in mind. Some lilies root from the base 

 of the bulb only, while others throw out later 

 a second set of roots from the stem a little way 

 above <the bulb. As the stem-roots are vital ele- 

 ments in the production of perfect bloom, the 

 stem-rooting lilies must be planted deep enough 

 to avoid exposure of this second set. It is diffi- 

 cult to draw a precise line between the two 

 classes, but a fair division, with the inches of 

 soil above the bulb, is as follows :
