Trees, Shrubs, and Woody Climbers 25 



autumn and winter months. Flourishes in sandy soils, and also near 

 streams, &c. Increased by layers and seeds. 



Hydrangea. A genus of ornamental shrubs with deeply veined leaves 

 and large trusses of flowers, which are sometimes all sterile and sometimes 

 sterile and fertile together. H. Hortensia and H. paniculate, are largely 

 grown as pot plants for market (see Vol. II, p. 175), but are perfectly hardy 

 in the open air in the milder parts of the kingdom, flourishing in any good 

 garden soil. Other kinds are arborescens, quercifolia, and radiata, from 

 North America; and petiolaris (scandens), from Japan. The last-named is 

 a climber with large trusses of white flowers; it requires sheltered spots. 



Hymenanthera crassifolia (fig. 425 ). An ornamental New Zealand 

 shrub, 2-4 ft. high, resembling a white-berried Cotoneaster when in fruit 

 in autumn. It flourishes in sandy peat 

 and loam, and is increased from cut- 

 tings or seeds. Quite hardy in the 

 milder parts of the kingdom. 



Hyperieum. Of the 160 species 

 known only a few are of commercial 

 value. Some of the best known are 

 Androscemum, the Common British 

 Tutsan or Sweet Amber, 1-2 ft. high, 

 remarkable for the scent of its dried 

 leaves; calycinum, commonly called the 

 Rose of Sharon, an almost evergreen 

 species, about 1 ft. high, and flowers 

 3 in. across; Moserianum, a hybrid 

 between calycinum and patulum, and 

 having a pretty variety called tricolor, 

 the leaves of which are blotched with 

 green, white, and rosy carmine; rather 

 tender; ffookerianum (oblongifolium), 

 from Nepal, is an evergreen, 2-4 ft. high; patulum, a rather tender 

 Japanese plant, 6 ft. high; perforatum, British St. John's Wort; and 

 uralum from Nepal, 2 ft. all with glossy yellow flowers and numerous 

 conspicuous stamens. Most of them grow in any soil, and are useful for 

 furnishing banks, beneath trees, &c. Propagation by cuttings and seeds. 



Idesia polycarpa. A rather tender Chinese tree, with large heart- 

 shaped serrated leaves, and long drooping racemes of yellowish flowers 

 the males on one plant, the females on another. Increased by cuttings 

 under glass. 



Ilex Aquifolium (HOLLY). The Common Holly and its numerous 

 varieties are always favourites, owing to their ornamental glossy-green, 

 silver, or golden foliage, and their masses of scarlet or orange-yellow berries 

 in winter. They flourish in good loamy soil, and are extensively pro- 

 pagated from seeds, cuttings, layers, and grafts by nurserymen. The 

 common kind is raised from seeds and is largely used for hedge purposes
