364 GARDEN FLOWERS. 



about June turn yellow, and die down, but little bulbs will 

 have formed : some take them up and replant them ; but, if 

 they are not too thick, they may be left until the next year. 

 It will be five or six years before they bloom. The Van 

 Thol Tulip, a pretty early sort, is the 2\ siiaveolens : this 

 blooms naturally in April, and is very well adapted for 

 forcing even much earlier than this. Few of the other 

 species are cultivated except as curiosities.
