BULB LITERATURE. 



The literature of bulbs is exceedingly varied and exhaustive, but 

 commonly not available to the average reader. American writings 

 are fragmentary, although they also are quite voluminous. In 

 spite of these facts, anyone with a little effort may get in touch with 

 abundant sources of information on the subject. There are four 

 main sources to consult — 



(1) Florist, horticultural, and agricultural papers. These are I'eplete with 

 writings on various phases of the subject, and every issue of many of them 

 carries advertisements of bulb literature. 



(2) Of bulb books there are many. They are exhaustive and comprehensive 

 and written in English. A few are American, but most of them are of British 

 origin. 



(3) Florist catalogues contain succinct and pointed information regarding 

 the handling of bulbs for decoration. Some of the larger houses issue sepa- 

 rate leaflets and pamphlets on methods of culture. These may be had for the 

 asking when purchasing bulbs. 



(4) The florists have the columns of their trade papers, as stated on a 

 previous page. Here are to be found the ci'ystnllized personal experiences of ex- 

 perts in the commercial production of florist materials. 



DEFINITIONS. 



Much of the information in bulb literature and even in popular 

 catalogues is in language quite strange to the uninitiated. Like 

 ever}^ other specialized line of endeavor, the bulb business possesses 

 a considerable language of its own. The following definitions will 

 assist in a better understanding of some of these expressions. 



Barrii. — A group of narcissi having small chalice-cupiJed coronas or trumpets. 



Bed. — A Dutch bulb bed is a meter wide, of any convenient length, but usually 

 about 10 meters (about 33 feet) long. 



Bicolor. — A trumpet narcissus with yellow trumpets and white perianth seg- 

 ments. 



Bizarres. — Tulips of various shades of scarlet to brown in the breeder and 

 broken sections, but, unlike the bybloemens, they have a yellow ground. 



Blower. — A machine or contrivance for removing the loose hvills and other light 

 material from bulbs. 



Breeders. — Tulips with self-colored flowers. The color of the base of the flower 

 is not taken into account.
