flowers, which are white, and about one and a half inches in diame¬ 
ter, are borne in clusters from four to six inches long, from June to 
September. It requires a sheltered situation, and a moist soil. In 
autumn the leaves turn to a fine deep-red color. 
The Heart-leaved Hydrangea, H. cordata , has large foliage 
and small flowers : the tree-like, H. arborescens , is a native of Penn¬ 
sylvania and Virginia; the bush, leaf, and flower being smaller 
than the preceding : the snowy-leaved, or hoary-leaved, H canescens, 
is a low shrub of the southern States, with flowers larger than the 
preceding, and leaves white and velvety beneath. The involucrata 
is said to be a hardy and unusually erect variety. 
The Japan Hydrangea. H deutziafolia (dl. paniculata gran- 
difiord). —This variety, but recently introduced into this country, 
bids fair to be quite the most valuable of the hydrangeas. It seems 
to be hardy in the Central Park, with straw protection in winter, and 
there forms magnificent masses of fine leaves and flowers, bloom¬ 
ing profusely from the first of August until frosts. The leaves are 
large, abundant, and of a dark bright glossy green color. The 
flowers are larger than those of the old box-hydrangea, of a creamy- 
white color, and waxy texture. They grow in immense spikes six 
inches or more long, and of equal breadth, and turn to a purplish- 
pink color as the season advances. Height and breadth of bush 
from three to five feet. 
THE HYPERICUM, OR ST. JOHNSWORT. Hypericum. 
Low sub-evergreen shrubs suitable for shady places. The va¬ 
rieties H. prolijicum and IP. kalmianum are broad, compact, low 
shrubs, two to three feet high, with small elliptical leaves, and 
corymbs of small yellow flowers in July and August, and are highly 
valued (especially the latter) for their neat compact growth and the 
warm tone of the foliage. The H. calycinum is an evergreen trail¬ 
ing species with much larger leaves and flowers, the latter of a 
bright-golden color, which is greatly esteemed for planting among 
rocks and trees in very shady places. The root creeps and stoles 
so that the plant extends itself rapidly over the surface.
