HEDERA (the old Latin name for the Ivy, used 
by Virgil and Pliny). Ivy. Orp. Araliacee, A genus, 
as now limited, containing but a couple of species of 
tall climbing shrubs, of which the one—in one or other 
of its numberless forms—is widely distributed throughout 
the Northern hemisphere, and the second confined to 
Australia. Flowers polygamous; umbels paniculate. 
Leaves undivided, lobed or pinnate, compound. Few 
plants are more serviceable in both large and small 
gardens than the old-fashioned Ivy, scarcely any situa- 
tion being unsuitable for it. In a good rich soil, growth 
is much more rapid than in a poor one; and strong 
plants, grown first in pots before placing out, well repay 
for the extra preparation thus made, by covering their 
allotted space in a much shorter time. Ivy is now ex- 
tensively used to cover open railings, as an arbour, as 
an edging plant, as a “screen” for a drawing-room, 
for hanging baskets, and in several other ways. When 
established, it is advisable to clip off all the old leaves 
annually, about April, as a close growth is thereby in- 
duced, and the old foliage is soon replaced by new. 
Propagation is readily effected by cuttings of any 
moderately firm young shoots, inserted in pots, or in the 
open ground, preferably in autumn. The tree forms and 
their numerous sports are grafted, any common strong- 
growing climbing form being used as a stock. The others 
may also be grafted, and the rarer variegated ones usually 
are, as this method of increase is a much more rapid one 
than cuttings. If cuttings are inserted in heat, and kept 
shaded until roots are formed, good plants are obtained in 
much less time than when placed in a cold frame, or in the 
open air,

shortly acuminate, often above bin. long, smooth and shining, but

een, SYN. H. viridis (S. H, Ivy, 99). There is a variegated 
orm of this, which, although not particularly attractive in 
a young state, is handsome when thoroughly established.

H. H. arborescens (arborescent). This is the “ tree” form of the 
common native Ivy of our woods and hedge banks, There are 
Sub-varieties, with ‘golden (see Fig. 183) and silyer variegation, 
and one with yellow berries,

H. H., canariensis (Canary Islands). Trish Ivy, This is the 
common large-leaved climbing Ivy—the best of all for quickly 
clothing walls, or for forming a green carpet under trees or on 
banks where grass, &c., refuses to grow. 1. deep green, usually 
five-lobed; terminal lobe largest. The fertile state of this, i.e., 
that which has outgrown the climbing stage, and produces flowers 
and fruit, has entire ovate leaves, and is propagated by grafting 
on the type; it is generally known in nurseries under the name 
of H. H. arborescens. SYN. H. grandifolia. There is a variegated 
form of this, but it is very apt to revert to the type.
