HELIANTHEMUM. 
change in its leaves when it flowers. 
The barren or creeping Ivy, which 
trails along the ground, and roots 
into it, rarely flowers, and its leaf is 
deeply cut; but the tree Ivy, or 
flowering part, rears itself on high, 
so as to be fully exposed to the light 
and air, and the leaves become of 
an oval shape. H. canariénsis, the 
giant, or Irish Ivy, as it is some- 
times called, though it is a native 
of the Canaries, is hardier and grows | 
much faster than the common kind ; | 
but the variegated kinds are more | 
tender, and grow much slower. Ivy 
requires a deep and somewhat light 
soil, into which its roots can pene- 
trate easily; and when grown for | 
any purpose, in pots or boxes, it 
should be abundantly supplied with | 
water. Ivy is useful in all cases 
where a naked space is to be covered 
with green in ashort space of time ; 
and it is particularly valuable in | 
town gardens, as it will bear the 
smoke and want of pure air in cities | 
better than most other plants. It 
should, however, in all close and 
crowded situations, be abundantly | 
supplied with water, and occasion- 
ally syringed overthe leaves. The 
gold and silver varieties are very 
beautiful, especially the former,when | 
grown against the chimney of a | 
dwelling-house or hothouse ; but they 
require warmth to make them thrive. 
Hencexocs.—Medicago minima. 
—An annual plant, with small 
yellow pea-flowers, and curiously- 
shaped capsules, which resemble 
hedgehogs. The plant is weedy- 
looking, and not worth growing.

Hepees for flower-gardens should 
be composed of ornamental plants, 
such as Cyddnia japonica, Pri- 
vet, Laurestinus, Ribes sanguinea, 
Roses, and double-blossomed Furze, 
or Ivy and other climbers, trained 
oxer iron trellis-work. The hedge 
‘to a flower-garden should never be 
stiff and formal, so as to look like a 
mere barrier; but it should be so 
arranged, and should consist of 
plants which harmonize so well with 
‘the flowers in the garden, as to 
‘make them appear a part of it.

Hepy’cuium. — Scitaminee. — 
Garland-flower. Large reed-looking 
plants with splendid flowers, but 
which are only suitable for large 
places, as they require the heat of a 
stove, and a great deal of room, to 
make them flower well. They are 
natives of the East Indies. H. co- 
ronarium, which is one of the com- 
monest kinds, has large white flow- 
ers, Which are exceedingly fragrant. 
All the kinds require a light rich 
soil, and are increased by dividing 
‘at the roots. 
Hepy'sarum. — Leguminodse. — 
|The French Honeysuckle. The ., 
species are mostly hardy biennials / 
and perennials, which require only 
the usual treatment of their respec- 
tive kinds. They will grow well in 
any rich light soil, and they are in- 
'ereased by division of their roots 
| and by seeds. 
Heve'nium.— Compéosite.— The 
‘species are generally tall-growing 
perennial plants, with large yellow 
flowers. They are increased by di- 
_viding the root. There are two or 
| three annual species which are quite 
_hardy, and only require sowing in 
'the open border. The handsomest 
of these is H. quadridéntum; which 
has bright erange-coloured flowers, 
| like a Rudbeckia. 
Hewia'/ntHEMuM. — Cistacee. — 
The Sun-rose. Low shrubs, gener- 
ally used for planting on rockwork, 
and strongly resembling the Cistus 
or Rock-rose. As most of the spe- 
cies are rather tender, they require 
protection during winter. For this 
reason, they are either grown in 
pots, which are placed on the rock-
