succession, so that a clump of them will be in continu- 
ous bloom from June until September. They can be 
increased rapidly from seeds or from offsets. ‘The bulbs 
must be kept dry und cool, but away from frost during 
winter, and planted with other summer flowering bulbs 
in spring. They also flower well during winter in the 
house, but they will not there take the place of winter- 
flowering bulbs.

CROCUS. 
This well-known genus of early spring and autumn 
flowers contains about ninety distinct species, but few of 
which, however, are now included among our garden 
flowers. The many choice varieties which are the results 
of hybridization, have taken the place of the species. 
The crocus is divided into two distinct classes, the spring 
and the autumn flowering. ‘The spring-flowering crocus, 
Crocus versicolor, is of the easiest culture ; but it is well 
to remark, that the too common practice of putting 
them into poor and badly prepared ground, is simply 
doing them great injustice. While they will flower with 
little or no care, they amply repay the best possible 
attention ; a well-prepared bed of deep rich soil is their 
delight. In such a soil the number of flowers will, at 
least, be doubled, and their size materially increased. 
They also want a dry situation; one where water stands 
during winter is fatal to the solid bulb or corm. 
Many complaints are made by amateurs of their 
Crocuses not flowering; there is really but one cause of 
failure when a new bed is made, and newly imported 
corms are planted ; that is, the work is too long delayed.
