RAISING FROM SEED 211 



this may be accomplished in outdoor cultiva- 

 tion by selecting an early site for the late- 

 flowering kind and a late site for the early 

 one, as discussed in Chapter II. By ad- 

 justing the regular forcing methods given in 

 Chapter III., types widely differing in time 

 of bloom may be brought to flower simulta- 

 neously. In this way, the poetaz race (the 

 result of crossing the late flowering N. poeti- 

 cus, var. ornatus with an early-flowering 

 Tazetta variety) was made possible. Also, in 

 the same way, the Sprengeri hybrids were pro- 

 duced by crossing a large yellow trumpet va- 

 riety with the Paper White. The Leedsii 

 varieties are crosses of the white trumpets 

 and poeticus. 



But it is not alone the crossing of species 

 and widely differing forms that gives us the 

 most valuable results. Most of the best large 

 new daffodils of the present time have been 

 produced by crossing individuals of the. same 

 group. King Alfred, the acknowledged peer 

 of the all-yellow trumpets — certificated in 

 1899 and still worth $15.00 per bulb — is a 

 cross between Maximus and Emperor, large 

 yellow trumpet daffodils. Other instances
