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. crispa 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. colurna, 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
