HARDY SHRUBS IN GREENHOUSE 273 



a fountain of yellow flowers. After flowering in the 

 greenhouse, cut back the shoots hard, leaving only 

 an eye or two at the base. These eyes will break 

 up and produce flowering shoots for another year. 

 By this method of treatment the same plants may 

 be kept for many years, provided they are carefully 

 attended to and given occasional doses of liquid 

 manure during the summer. 



HYDRANGEA. The many varieties of the common 

 Hydrangea are all valuable for the greenhouse, 

 particularly Cyanoclada, Mariesii, Rosea, Stellata, and 

 Thomas Hogg. To obtain small flowering plants 

 the cuttings are struck in spring or early summer, 

 grown on freely for a time, and well ripened by full 

 exposure to air and sunshine before autumn. Plants 

 grown in this way readily respond to a little heat 

 in the spring. Larger specimens, too, may be brought 

 on in the same way. The Japanese H. paniculata 

 grandiflora needs quite different treatment, the plants 

 being generally grown in the open ground, from 

 whence they are lifted and potted in the autumn. 

 Before potting prune the long, wand-like shoots back 

 hard, leaving only about two eyes at the base. By 

 so doing the plants are kept dwarfer, and the flower 

 heads are larger than if no pruning were done. By 

 some the Hydrangea is grown as a standard, and 

 is very effective when in beauty. 



ITEA VIRGINICA. A neat little bush, about a yard 

 high, with dense spikes of white flowers. It needs 

 a sunny spot in a cool and moist soil, and under 

 these conditions will flower freely if carefully lifted
