BULBS AND TUBERS 



203 



The lilies all flower in summer. They are all hardy, and 

 need not be lifted in fall. Put no manure near them. Of 

 the many kinds, differing in color, sizes, and seasons, the 

 following are the best : 



Lilium auratum, the golden-banded lily, is finest of all 

 (and most expensive!) Set them a foot apart, and ten or 

 twelve inches deep. They flower in July. See Fig. 56. 



Lilium specioswn, almost as fine, and hardier. Flowers in 

 Julv. Cover five inches ; _--7— ~^

 tuber.

Lilium canadense, the r X\ •■ l W/M 



Canada or meadow lily, 

 likes more moisture than 

 most bulbs. The yellow 

 and red flowers bloom in 

 May. Cover four inches ; 

 set nine inches apart. 



Lilium tigrinum, the 

 tiger lily, blooms in early 

 July. It can be raised 

 from the little black bulbs which grow on the stalk. Cover 

 the large bulbs four inches ; set nine inches apart. 



The Annunciation lily, lilium candidum, should be planted 

 in August or September for next summer's bloom. Cover 

 four inches or more ; set nine inches apart. 



All lily bulbs, when out of the ground, should be kept in 

 wet sand or moss, and not allowed to dry out. 



Besides bulbs, tubers can be planted in spring. These 

 give us the potato, our most important vegetable, and the 

 Jerusalem artichoke, with the canna and dahlia among 

 flowers. All of them take more space than the bulbs. Just 

 a word about each of them, remembering that all should be 

 set four inches deep, and that all must be lifted in the fall.
