HARDY ORNAMENTAL TREES AND SHRUBS. 



305 



Hymenanthera crassifolia (fig. 372). — A dwarf shrub 

 with short rigid branches and small linear -spathulate 

 leaves. The flowers are dull-yellow and small, but they 

 are succeeded by comparatively large white berries. 



Fig. 371.— Hydrangea paniculata grandiflora. 



Should be protected during severe frost. New Zealand 

 1875. 



Hypericum. — Dwarf shrubs with opposite, short-stalked 

 or sessile leaves, and yellow flowers with a conspicuous

cluster of stamens. Several of the species are sub-ever- 

 green, especially in mild winters. 



H. Androscemum, Tutsan. — This indigenous plant 

 deserves to be planted in shrubberies on account of the 

 pleasant odour of the dried leaves ; it grows from 1^ to 

 2 feet high. 

 Vol. I. 



H. calycinura, Rose of Sharon. — A dwarf shrub, with 

 trailing underground stems forming thick tufts, bearing 

 oblong glossy leaves, and showy yellow flowers from 2 to 

 3 inches in diameter. Valuable for covering banks, &c, 

 especially as it succeeds well in shady places and under 

 trees. South-east of Europe, now naturalized in Britain. 



H. hircinum. — A half -evergreen shrub 3 or 4 feet high, 

 flowering late in the summer and onwards till the end of 

 October. Spain, 1640. 



H. Hookerianum. — This grows 3 to 4 feet high, and is 

 the handsomest of the taller species. The flowers are 

 rich yellow, cup-shaped, and about 2 inches across. 

 Habit erect. North India. 



H. Kalmianum. — A North American species 2 to 4 feet 

 high, which flowers in the summer months. Introduced 

 in 1759. 



H. Moserianurn. — A hybrid between H. colycinum and 

 H. patulum, having large golden-yellow flowers. It com- 

 mences to blossom in July and continues for two months. 

 It is killed to the ground in hard winters, and in severe 

 weather should be covered by a thick layer of dry leaves. 



H. patulum. — A very graceful plant, its slender stems 

 bearing ovate pointed leaves and corymbs of bright-yellow 

 flowers. Tender except in the south. Japan. 



Idesia polycarpa (Polycarpa Maximoiciczii). — A tree 

 of considerable size, with large cordate leaves and ter- 

 minal panicles of small flowers, succeeded by clusters of 

 purplish-black berries. Hardy only in the south and 

 west. Japan, 1869. 



Ilex. — The Hollies constitute a large genus spread 

 over almost the entire globe. The species that are hardy 

 in Britain number about a dozen, but the variety of the 

 genus is enormously increased by the numerous forms of 

 the common Holly. The perfect hardiness of these, their 

 glossy, deep-green or variegated leaves, and their bright 

 red or yellow fruits, render them perhaps the most useful 

 of evergreens. The Holly is one of the best of our hedge 

 plants. 



7. A quifolium, Holly.— Of the numerous named varieties 

 the following are the most distinct and handsome : Green- 

 leaved : camellicefolia, Doningtonensis, ferox (hedgehog), 

 Hendersonii, Hodginsii, ovata, pendida, platyphylla, Shep- 

 herdii, tortuosa, and Whittingtonensis. Silver- variegated : 

 argentea rnarginata, ferox argentea, argentea medio-picta, 

 Silver Queen. Golden - variegated : aurea marginata, 

 Golden Queen, Golden Milkmaid, Hodginsii aurea, 

 Waterer's. These varieties are increased by budding on 

 the common Holly, or by cuttings. 



/. cornuta (fig. 373). — A very striking species, usually 

 seen in the form of a rounded shrub. The leaves are 

 stiff, very dark green, and armed with five or seven stout 

 spines. China, 1850. 



I. crenata. — A slow-growing compact bush with small, 

 ovate, crenate leaves under 1 inch in length. Used as a 

 hedge plant in Japan. Strikes readily from cuttings in 

 autumn. 



I. latifolia and I. Integra are two handsome Japanese 

 species, the latter with unarmed leaves. 



1. opaca (fig. 374). — The leaves of this are dull-green, 

 ovate, with a few teeth on the wavy margins. North 

 America, 1744. 



Indigofera Gerardiana. — An elegant, slender, branched 

 shrub, very suitable for planting against a wall or in the 

 open, where, however, it is usually cut back to the ground 

 in winter. In spring it sends up freely its graceful shoots 

 2 to 3 feet high, clothed with delicate pinnate foliage. 

 The flowers are rose-purple, and produced freely in late 

 summer in erect racemes. North India.
