ceous perennials, giowing five or six feet liigli, and bearing 

 white, orange, scarlet, or yellow flowers. Soil, turfy loam, 

 peat, old dung, in equal proportions, with a liberal allowance 

 of coarse sharp sand. The plants should be fresh potted in 

 January or February, having been previously rested by being 

 kept drier and cool during winter. Turn out the plants, take 

 off the suckers, and repot the roots in appropriate-sized pots, 

 not larger than necessary, in order that when the first pot is 

 filled with roots it may be exchanged for one of larger size. 

 They require through the growing season a liberal supply of 

 water. When tlje colours are showing they should be put in 

 the coolest part of the stove, that they may be prepared for 

 i-emoval to the conservatory. From the time the bloom 

 decays they should be allowed to rest, receiving but little 

 water ; they would, in fact, do in the greenhouse until the 

 repotting time. The period of blooming is some time during 

 the latter part of the summer, according to the time when 

 they are excited, and the rapidity with which they are grown. 

 There are numerous species, but the most popular are H. an- 

 (^u.stifoUum, scRr\et; H. aurantiacum, orange; li. coronarium, 

 white; H. flavescens, yellowish; H. Gardnenanum, yellow; 

 and H. speciosum, pale yellow. 



HEDYSARUM. [Leguminosse, § PapilionaceaB.l Hardy 

 herbaceous plants, including annuals, biennials, and peren- 

 nials. Common garden soil. Increased by seeds or division. 



HEIMIA. [Lythraceae.] Greenhouse deciduous shrubs. 

 Soil, sandy loam and peat. Increased freely by cuttings in 

 heat. 



HELIANTHEMUM. Sun Rose. [Cistacere ] Small 

 evergreen shrubs, immediately related to Cistus, mostly trail- 

 ing plants, and among the prettiest ornaments of rockwork. 

 The genus comprises more than a hundred species and 

 varieties, some requiring a frame, but the greater part nearly 

 hardy : a few are hardy annuals. They grow chiefly upon 

 rocks and rockwork, and therefore require hard dry ground. 

 The poorer the loam in which the plants are grown the better: 

 a mixture of sandy loam with a little peat is suitable. They 

 are best on rockwork and on banks. The annuals may be 

 sown thinly on the ground of the common border. The 

 shrubby kinds are raised from cuttings, and want but little
