Bulbs of the genus Lilium, of which there are approximately 50 

 species, are like most other bulbs in giving best results if planted 

 when received. However, as Easter lilies are forced during the entire 

 year, it becomes necessary to provide cold-storage conditions suitable 

 for satisfactory holding until they are wanted for planting. The 

 bulbs should be packed in boxes in thoroughly dry soil if rooting and 

 desiccation are to be prevented. A temperature of 35° F., with a 

 relative humidity of 75 to 80 percent is recommended. 



Tulips are usually not stored in any packing material, although the 

 use of such material may be advantageous for long storage. Tem- 

 peratures of 36° to 38° F., except for short storage, are considered 

 rather low for tulips shipped in from the West in which the buds are 

 already formed. The best storage temperature for shipped tulips is 

 between 50° and 55°.
