 bulbs of a flowering size. 



Tulips are usually listed by dealers under the 

 heads of early single tulips, early double tulips, 

 late double tulips, parrot tulips, late garden or 

 May-flowering tulips and Darwins. The best 

 early singles for outdoor planting are the fol-

 bright scarlet ; Brutus, scarlet ; Rose Gris-de-lin, 

 the best bright pink; C'hrysolora, the best early

 white; Couronne d'Or, yellow; Duke of York, 

 carmine with white edge; Rex Rubrorum, 

 bright scarlet; Couronne des Roses, deep pink. 

 These are all early varieties of the double class ;
