tint from white (to/its albus] to crimson 

 and purple, while the blooms of one sort 

 (Celeste] are almost blue. There are also 

 double flowers of varied colours. The 

 best kinds, single and double, are Totus 

 albus, Celeste, Violet Clair, Leopoldi, 

 bicolor, roseus plenus, Pompon Rouge, 

 carneoplenus, Du^ de Brabant, albus 

 plenus, puniceus plenus, and anemonce- 

 florus. 



In the South German gardens this 

 shrub assumes a larger growth, and bears 

 much larger flowers than in England. 

 The usual form has 

 flowers not so attrac- 

 tive in colour as some 

 of the newer forms 

 raised from seed main- 

 ly in France, and there 

 are some double kinds 

 poor in colour and ef- 

 fect. The pure white 

 kind (totus albus] and a 

 few others lead to the 

 hope that it is a plant 

 capable of real improve- 

 Hibiscus syriacus. ment through raising 

 seedling forms, and 

 perpetuating the best of them. Our 

 experience of this shrub in our own 

 islands is that it is best on free and warm 

 soils ; not too dry. Where it thrives it is 

 well worth more attention than is usually 

 the fate of flowering trees in the British 

 shrubbery ; all the more so now that we 

 are getting varieties of good colour like 

 the pure white one named above, and 

 Celeste. 



HIERACIUM (Hawkweed\ Peren- 

 nial herbs with yellow flowers, very numer- 

 ous, and often beautiful in nature, but not 

 much grown in gardens. Among the best 

 are aurantiacum with orange flowers, a 

 good plant, but apt to spread too much in 

 the garden ; and villosum, the Shaggy 

 Hawkweed, a handsome plant with silvery 

 leaves and large yellow flowers. Free in 

 ordinary soil. Borders. Division. Daisy 

 order. 



HIPPOPHJE (Sea Buckthorn). H. 

 rhamnoides is a beautiful seashore native 



the rich 



ly soil but hungry clay and peat. 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, which, when the shrub 

 is sheltered, rises 8 or 10 ft. high. In 

 gardens it grows taller. The Sea Buck- 

 thorn has silvery-looking Willow-like 

 leaves and bears a profusion of orange 

 berries. 



rnajnnoiaes is a oeauinui seasnore native 

 shrub, developing its full beauty in the ricl 

 soils of inland gardens, though it is happj 

 in any soil but hungry clav and peat. Th< 



HOLBCELLIA. //. lati folia is a beau- 

 j tiful 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 a 

 deliciously fragrant 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. It is 

 known also as Stauntonia latifolia. The 

 variety angustifolia has smaller and more 

 numerous leaflets. 



HORDEUM. Grasses, of which the 

 Barley is the most familiar type, few of 

 ornamental value except H. jubatum 

 (Squirrel-tail Grass), which has long 

 feathery spikes. It grows in any soil in 

 open places, is easily raised as an 

 annual, and is one of the most distinct 

 dwarfer Grasses. Sow in autumn or 

 spring. 



HOTEIA. H.japonica is a fine tufted 

 herbaceous plant i ft. to 16 in. high, with 



Hippophae rhamnoides. 



! 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.
