HELICO^IA. 



pea-flowers, and curiously shaped cap- 

 sules, which resemhle hedgehogs. The 

 plant is weedy-looking, and not worth 

 growing. 



Hedge Mustard. — See Er/ysimum. 



Hedge Nettle. — See Stachys. 



Hedges for flower-gardens should 

 be composed of ornamental plants, 

 such as Cydonia japonica, privet, lau- 

 restinus, Rlbes sangmnum, roses, and 

 double-blossomed furze, or ivy and 

 other climbers, trained over iron trel- 

 lis-work. The hedge to a flower- 

 garden should never be stiff and formal, 

 so as to look like a mere barrier ; but 

 it should be so arranged, and should 

 consist of plants which harmonize so 

 well with the flowers in the garden, 

 as to make them appear a part of it. 

 For farther details on this subject see 

 Fences. 



Hedy'chtum. — ScitaminecB. — 

 Large reed-looking plants with splendid 

 flowers, but which are only suitable 

 for large places, as they require the 

 heat of a stove, and a great deal of 

 room, to make them flower well. They 

 are natives of the East Indies. H> 

 coronarium, which is one of the com- 

 monest kinds, has large white flowers, 

 which are exceedingly fragrant. .All 

 the kinds require a light rich soil, and 

 are increased by dividing at the roots. 



Hedy'sarum. — Leguminosce. — 

 The French Honeysuckle. The 

 species are mostly hardy biennials 

 and perennials, which require only the 

 usual treatment of their respective 

 kinds. They will grow well in any 

 rich light soil, and they are increased 

 by division of their roots and by 

 seeds. 



Hele nium. — Composites. — The 

 species are generally tall-growing per- 

 ennial plants, with large yellow 

 flowers. They are increased by divid- 

 ing the root. There are two or three 

 annual species which are quite hardy, 

 and only require sowing in the open 

 border. The handsomest of these is 



H. quadridentum, which has briglU 

 orange-coloured flowers, like a Rud- 

 beckia. 



Helia'nthemum — Cistacece. — The 

 Sun-rose. Low shrubs, generally used 

 for planting on rockwork, and strongly 

 resembling the Cistus or Rock-rose. 

 As most of the species are rather ten- 

 der, they require protection during 

 winter. For this reason, they are either 

 grown in pots, which are placed on the 

 rockwork among the stones ; or taken 

 up and repotted in winter, to be 

 planted out again in spring. The soil 

 should be a compost of loam and peat, 

 They are generally increased by seeds, 

 which they ripen in abundance. 



Helia'nthus. — Composite. — The 

 Sunflower. The annual plant of this 

 name, though a native of Peru, is of 

 the hardiest of its kind, as it only 

 requires sowing in the open border in 

 any common garden soil. It is not, 

 however, suitable for any situation, 

 unless there be abundance of room, on 

 account of the large size of its stalks 

 and leaves. The perennial kinds are 

 much smaller, and very ornamental : 

 they are quite hardy, and will grow in 

 any soil and situation. 



Helichry v sum. — Composite. — 

 The Everlasting. The common yel- 

 low everlasting, H. bracteatum, is a 

 hardy annual that only requires sowing 

 in the open border ; H. bicolor is a 

 very slight variety, merely differing in 

 having the outer petals tipped with 

 copper colour ; but H. macranthum 

 has white flowers tipped with pink, 

 and is very handsome. This species i3 

 a native of the Swan River colony, and 

 it should be grown in a light peaty 

 soil. It may either be sown in the 

 open ground in April, to flower in 

 autumn, or in a hot-bed in February, 

 to plant out in May. 



Helico^nia. — Musacece. — Splendid 

 hothouse plants, which require a rich 

 sandy loam, and plenty Gf room and 

 heat, to bring them to perfection. They
