502 HIPPOPH*.. THE ENGLISH FLOWER GARDEN. 



HOTTONIA. 



upper petal faintly veined with brown, 

 the pinnate leaves small and leaflets 

 smooth. It is a capital little plant 

 for the upper ledges of rocks in dry 

 positions, as in such places the shoots 

 will fall down some 18 or 20 inches ; 

 it is easily raised from seed ; partial to 

 chalky soils ; and is rather common 

 in the south of England, but not a 

 native of Ireland or Scotland. 



HIPPOPHZE (Sea Buckthorn). H. 

 rhamnoides is a beautiful seashore 

 native shrub, happy in any free soil. 

 The best position for it is a rather 

 damp spot near a running stream, 

 where the subsoil is always moist. It 

 forms, when wild, a straggling bush, 

 8 or 10 feet high. In gardens it grows 

 taller. The Sea Buckthorn has silvery- 

 looking Willow-like leaves and bears 

 a profusion of orange berries. Apart 

 from th? brilliantly coloured fruit, the 

 silvery effect of the leaves is good 

 where the bush thrives. There are 

 other kinds, H. fasciculata and H. 

 salicifolia, natives of Indian mountains, 

 but they are so far rare in gardens. 



HOHERIA POPULNEA (New Zea- 

 land Ribbon - wood}. An evergreen 

 shrub from New Zealand, in flower and 

 habit like a coarse-leaved Deutzia, and 

 not at all like the Mallows, to which 

 it is related. It is hardy in the warmer 

 parts of Ireland and in the south-west 

 of England, a fine plant 10 feet high 

 having flowered in the Trinity College 

 Gardens, Dublin, for several years past. 

 The pure white flowers are borne 

 freely in clusters in autumn, and the 

 sharply-tapering dark green leaves are 

 deeply toothed. New Zealand. Seed 

 or cuttings of the young shoots in 

 spring. 



HOLBCELLIA. H. latifolia is a 

 beautiful evergreen climbing shrub 

 from the Himalayas, hardy against 

 walls in the southern and the warm 

 districts. The foliage is thick, with 

 three or five leaflets of a deep shining 

 green. The flowers are deliciously 

 fragrant and in colour dull purplish 

 green, but it does not bloom so freely 

 out of doors as in a cool conservatory. 

 As it is of tall growth, it must be 

 planted against a" high wall, such as 

 that of a house or stable. 



HOMERIA COLLINA. A choice 

 bulbous plant from the Cape, thriving 

 in such light southern soils as suit 

 Sparaxis, Ixia, and the like. The 

 flowers, in finely blending tints of 

 orange or salmon pink shaded with 



purple about a yellow eye, are 2| inches 

 across and borne four or more together 

 on stems of 2| feet. They close to- 

 wards evening until morning. The 

 leaves are 4 feet long and half an incli 

 wide, and are so succulent that unless 

 I carefully protected from snails they 

 are soon eaten through. The bulbs 

 increase rapidly in warm open soils, 

 and they may be left in the ground 

 with a covering of ashes in the south. 

 Seed ripens freely, and germinates 

 without any trouble in sunny seaside 

 gardens. 



HORDEUM. Grasses, of which the 

 Barley is the most familiar type, few 

 of ornamental value except H. jubatum 



I (Squirrel-tail Grass), which has long 

 feathery spikes. It grows in any soil 



I in open places, is easily raised as an 

 annual, and is one of the most distinct 

 dwarf er grasses. Sow in autumn or 

 spring. 



HORMINUM PYRENAICUM. A 



Pyrenean plant, forming dense tufts 

 of foliage, and having purplish-blue 

 flowers, in spikes about 9 inches high, 

 which appear in July or August. It 

 is hardy and of easy culture, but is 

 not a plant of much effect from a 

 garden point of view. 



HOTEIA. H. japonica is a fine 

 tufted herbaceous plant i foot to 

 1 6 inches high, with silvery - white 

 flowers early in summer in a panicled 

 cluster. In a rich soil it is excellent 

 for a shady border. Strong clumps 

 planted in autumn will flower in the 

 following spring. Where there are 

 forced plants to spare they may be 

 planted out when they have done 

 blooming, but will not make much 

 show in the following season. Much 

 used indoors ; is seldom good in the 

 open garden, partly because it does 

 badly in heavy and poor soils. Where 

 it thrives and flowers well it would be 

 a graceful aid in the varied flower 

 garden. Increased by division in 

 autumn. Japan. Syns. Spircea japo- 

 nica, Astilbe barbata. Henry's variety 

 of H. japonicum is found to be a very 

 good plant. 



HOTTONIA (Water Violet}. H. 

 palustris is a pretty British water- 

 plant, which, however, thrives better 

 on soft mud-banks than when sub- 

 merged. The deep-cut leaves form a 

 dwarf deep-green tuft over the mud, 

 and from this tuft arise stems bearing 

 at intervals whorls of handsome pale 

 lilac or pink flowers. As water an4
