part its color to the leaves of the stock on which it is grafted! It 
might be grafted or budded on strong canes of our native hazel. 
The C. a. crisfia is one of the finest filberts, and also remarkable 
for the length and showiness of its fringed nut-husks. The C. a. 
tennis , C. a. tubulosa , C. a. barcelonensis, are all fine large varieties 
of filberts, and somewhat larger shrubs than our native hazel. 
The Constantinople Hazel, C. column , is the largest of the 
species, making a tree fifty to sixty feet high. 
THE HYDRANGEA. Hydrangea. 
Herbaceous shrubs, mostly natives of this country, some of 
which have globular masses of white and pink-white flowers, and 
generally fine masses of large, rather heart-shaped leaves, of a 
pleasing light-green color. Generally half-hardy. 
The Garden Hydrangea. H. hortensis. —This is the common 
bushy plant grown in boxes and seen in or near almost every New 
England village porch. It is well worthy of its popularity. Few 
plants better repay attention. It forms a globular bush, from two 
to four feet in diameter, densely furnished with large leaves, and 
covered all summer with light pink blossoms, in massy clusters, 
frequently six inches in diameter. The flowers change their color 
in an unusual manner with the treatment they receive, sometimes 
changing to blue and purple; a mixture of a few iron-filings with 
the soil producing the former color. It is best to grow it in boxes, 
to be wintered in dry cellars, as it is too tender to be trusted in the 
open ground in the northern States. It is one of the most beauti¬ 
ful outdoor box-plants, of easy culture, and as it does best in the 
shade, is peculiarly adapted to positions near walks in the shadows 
of trees. It requires rich, warm, and always moist soil. 
The Silver-striped Leaved, and the Golden-striped Leaved 
Hydrangeas, have only the peculiarities which their names import. 
The Oak-leaved Hydrangea. H. quercifolia. —A hardier 
shrub than the hortensis , and more woody; of bushy habit. It be¬ 
comes a massive-looking shrub, six feet high. The leaves are 
large, rough, lobed like an oak, and hairy or downy beneath. The
