EVERGREEN VINES 131 
Ivy climbs to an immense height. It is diffi- 
cult to find a definite figure stated by any writer, 
but to say one hundred feet would not I think be 
overstating its possibilities. In case the plant 
seems subject to sun scald injury during winter, 
the removal of the leaves in early spring as 
described in a previous paragraph, will not only 
remove any effects of scalding, but will also 
induce a more compact and more vigorous 
growth. 
There is a multitude of varieties of ivy, of 
which I shall mention but a few of the best. 
The common type (Hedera Helix proper) has 
dark-green leaves, somewhat pale underneath. It 
is a very free grower and will succeed almost any- 
where. H. Helix var. Algeriensis has leaves almost 
round, and of a much lighter green. The leaves 
of var. Cavendishi are attractively edged with 
white, and become a brilliant colour in the fall; 
but the vine is not as rank a grower as the above- 
mentioned varieties. H. Helix var. Hibernica has 
the largest leaves of any of the family; these are 
also of a unique shape, being often broader than 
they are long. Any of these varieties can be 
grown as far north as New York, if given a little 
protection in winter.
