G. rosmarinifolius, bearing red flowers in summer and with 
rosemary-like foliage, and R. sulphurea, with juniper-like 
foliage and yellowish flowers, are the only two species that 
succeed outdoors, and these do best against a west wall. 
Ordinary light sandy loam will suit them. Plant in April or 
May. G. robusta, a greenhouse species with fern-like foliage, 
is used for summer bedding. The plants are plunged in their 
pots in June and removed indoors in September. Increased by 
seeds sown in heat in spring. 
Halesia (Silver Bell or Snowdrop Tree). — Hardy deci- 
duous flowering trees, natives of N. America, and members of 
the Nat. Ord. Styracaceae. The best-known species is H. tetra- 
ptera, and this is really the only one worthy of general 
cultivation. It grows 15 to 20ft. high, has a compact habit 
of growth, and bears pure white snowdrop-like flowers in May. 
This tree is a striking object when in flower, and a handsome 
tree for growing on the lawn or in the pleasure grounds. 
A fine specimen of it is to be seen in the gardens of Buxted 
Park, Uckfield, Sussex. The soil in this case is heavy Wealden 
clay, but well drained. Any good ordinary soil not too dry will 
suit it. We have also seen it thriving well by the side of a 
lake. Plant in autumn. Increased by seeds sown in sandy 
soil in a cold frame in spring ; by cuttings of shoots inserted 
in sandy soil under a handlight in autumn ; and layering in 
October. 
Halimodendron (Salt Tree). — A genus of dwarf de- 
ciduous flowering shrubs, belonging to the Pea family (Legu- 
minosae). H. argenteum, the only species, has silky white 
pinnate leaves, and purple flowers borne in umbels in summer. 
It grows 4 to 6ft. high, and is a native of Asiatic Russia. 
Grafted on the Laburnum, or Caragana arborescens, and grown 
as standards, this shrub forms a pretty object. May be grown 
in the mixed shrubbery, or in beds of choice shrubs. Ordinary 
soil. Plant in autumn. Increased by seeds sown outdoors in 
autumn ; cuttings or layering in autumn. 
Hamamelis (Witch Hazel). — Hardy deciduous flowering 
shrubs, blooming in winter, and belonging to the Nat. Ord. 
Hamamelidacese. The most noteworthy species are : H. arborea, 
flowers yellow, calyces crimson, petals twisted, height 10 to 
15ft., Japan; H. japonica, flowers yellow, calyces purple, 6ft., 
Japan; H. mollis, flowers bright yellow, 6 to 8ft., China; H. 
virginica, flowers rich yellow, height 6ft., N. America. The 
great charm of the Witch Hazels lies in their flowering in 
winter whilst the twigs are leafless. These shrubs thrive in 
any good soil, and should be grown in the mixed shrubbery in
