CHAPTER II 
RAISING ANNUALS IN GREENHOUSE OR 
FRAME 
By E. H. Jenkins 
I 
Annuals roughly divide themselves into three 
classes : “ hardy,” those which may safely be 
sown in the open air; “half-hardy,” those 
which should be raised in greenhouse or frame 
and subsequently transferred to the open ground ; 
and “ tender,” such as require to be raised and 
grown under glass, to bring them to perfection. 
It should be stated, however, that quite a 
large number of the obviously hardy kinds are 
annually sown under glass, some for convenience ; 
others, and these largely in the majority, for 
market work or commercial purposes. Others, 
too, as Pentstemons and Antirrhinums, which, 
being perennial, have no claim to be classed 
among annuals, give such excellent results when 
treated as such, that each year considerable 
quantities are sown in warmth under glass
