one pot and growing them through the 
autumn in a lively moist heat, fine spe¬ 
cimens, clothed with foliage and crowned 
with large spikes of brilliant orange and 
scarlet flowers, will result. 
GENISTA (Lamarck.) Nat. Order 
Leguruinosce . A genus of handsome 
greenhouse and hardy shrubs, of rapid 
growth, copious habit of blooming, and 
easy management. The greenhouse kinds 
should be cultivated in large pots of 
peat and loam; they require plenty of 
water in summer, and should be fre¬ 
quently stopped while young to induce 
a dwarf compact habit; the best of them 
are Attleana , Canariensis , and rodophne. 
The hardy species are appropriately 
placed in the front of shrubbery borders, 
where they form dwarf free-flowering 
subjects, highly ornamental. All the spe¬ 
cies, with only one exception, have yel¬ 
low flowers; that one is G. aphylla , a 
hardy deciduous shrub with violet blos¬ 
soms. 
GENTIAN A (Linn.) Nat. Or. Gen- 
tianacecc. An extensive group of really 
lovely, little, hardy, herbaceous plants, 
well deserving every attention. The 
perennial species delight in a rich loamy 
soil slightly shaded from the burning in¬ 
fluence of the summer’s sun, and the 
biennial and annual should be sown as 
soon as the seed is ripe in autumn, lest 
it fail to vegetate; these prefer a dry 
sandy soil. There are a few which, from 
their rarity rather than an inherent ten¬ 
derness, are protected through the win¬ 
ter in cold frames. The following are 
a few of the most beautiful: acaulis, 
alpina, altcdca, biloba, Catesbcca, incar- 
nata, pumila, and purpurea albo. 
GERANIUM (Linn.) Nat. Ord. Ge- 
raniacece. This genus formerly contained 
both Pelargonium and Erodium, but as 
now constituted is a collection of, for the 
most part, hardy herbaceous plants, some 
of which produce interesting lively co¬ 
loured flowers, while others are mere 
weeds; they grow in almost any soil or si¬ 
tuation. The tender species, such as G. 
anenioncefolium, G. argenteum , and G. ca- 
nescens , require to be grown in loam, 
peat, and leaf-mould, and to have the 
protection of a good pit in winter. 
GESNERA (Linn.) Nat. Ord. Ges- 
neracece. These splendid plants are or 
ought to be universally grown; their 
brilliant crimson, scarlet, yellow, or 
white flowers, large in size, copiously 
and gracefully produced, together with 
the rich velvet-like foliage of the bright¬ 
est green, render them almost without a 
rival, nor is the attention requisite to 
produce all this loveliness of an amount 
or kind to require the expenditure of 
either much time or skill. In winter 
the roots should be kept perfectly dry 
and dormant; in early spring they are 
potted into light sandy peat and leaf- 
mould, and placed in a brisk heat, such 
as that afforded by a cucumber bed or 
the shelves of a forcing-house; here they 
quickly grow, and by the approach of 
summer commence the development of 
their lovely blossoms; a cooler place is 
then most fitting, and by the tune the 
flowers are fading, the season of growth 
will be complete, and the bulb must 
again be dried for hybernating. The 
following are desirable kinds: Cooperi , 
Douglassi , faucialis, Merckii, splendens, 
Suttonii, and Zebrina; the last flowers in 
winter. 
GEUM (Linn.) Nat. Ord. Rosacece. 
Beautiful, hardy, herbaceous plants, de¬ 
lighting in rich soil and an open situa¬ 
tion, where they display their numerous 
pretty flowers to great advantage. G. 
coccineum, atrosanguineum , and Hop- 
woodii, deserve a place in every garden. 
GILLIA (Ruiz and Payon.) Nat. 0. 
Rolemoniacece. Pretty annuals, perfectly 
hardy, and, with one exception, merely 
require to be sown where they are to 
bloom. G. aggregata , the one referred 
to, perhaps better known as Ipomopsis 
elegans, being a biennial requires to be 
sown about Slay, and preserved in pots 
in a cold frame through the winter, in 
order to have it in good condition for 
planting into the borders in the follow¬ 
ing April. G. tricolor , tenuifolia , and 
gracilis , form excellent substitutes for a 
more permanent edging to flower beds. 
They are dwarf, and most abundant 
bloomers. 
GLADIOLUS (Linn.) Nat, Order 
Iridacece. These plants should be cul-
