HOLLAND BULBS. 



The Holland Bulbs, comprising the Hyacinth, Tulip, 

 Crocus, Snowdrop, Jonquil, Narcissus, Iris, and Frittil- 

 laria, are all hardy in this section of the country, although 

 it is always advantageous to cover them with three or 

 four inches of short manure, refuse hops, or sawdust, as a 

 protection from being too severely frozen, as this, in cold 

 and heavy soils, may sometimes injure their flowering. 



All Holland Bulbs prefer a rich sandy soil, in preference 

 to one of heavy clay. They are usually imported annual- 

 ly, although, with the exception of the Hyacinth, they 

 can all be grown and increased to advantage in our own 

 climate. 



The bulbs are usually planted in the open ground in 

 October, Hyacinths at distances of 9 inches apart, Tulips, 

 Narcissuses, and Jonquils at 6 inches, Crocuses and Snow- 

 drops, to produce a good effect, at 3 inches. They are 

 best grouped in beds of each sort by itself to show to ad- 

 vantage. As soon as their flowering is over in spring, 

 Verbenas or other bedding plants should be placed in the 

 beds, as the bulbs are not sufficiently ripened to lift before 

 June or July. When the leaves by becoming withered 

 indicate the ripening of the bulbs, they should be lifted,
