failed, or were so bad as to afford but little 
benefit. 
6th. Applied to dahlias on poor ground, 
they grew twice the size of their fellow plants 
in the same soil, watered at the same times, 
but not with ammonia water. 
7th. Applied every third day's watering, it 
made the plants turn yellow, some of the 
leaves drop, and remain sickly for weeks, after 
which they recovered and grew remarkably 
fast and well. 
From these gathered facts we have a right 
to believe that this, as well as many other ap- 
plications, depends for its efficacy on the proper 
quantity being administered, and as there can 
be nothing so certain as the uniform strength 
of the liquid to begin with, and the application 
of it according to the quantity of water admi- 
nistered for nourishment, there can hardly be 
a safer mode. In winter, plants want but 
little moisture, perhaps hardly once a week, 
but if once a week, every sixth week should 
have the ammonia water ; and if twice a week, 
its turn would come every third week. But 
there can be no mistake, when it is understood 
that they are to be watered five times with 
plain water to once with the solution, and that 
solution is to contain half an ounce of sulphate 
of ammonia to one gallon of water. 
BIGNONIA RADICANS. 
ASH-LEAVED TRUMPET FLOWER. 
We hardly know a climbing plant that de- 
serves more general attention than the Big- 
nonia radicans. It requires but little trouble; 
it soon covers a large space ; it clings of itself 
like ivy, and only wants to be kept within the 
prescribed bounds. The magnificent Ipomea 
Horsefallii, with its rich scarlet-crimson trum- 
pet-mouth flowers, the admiration of our stove 
conservatories, presents not an object more 
brilliant than does this easily-grown plant, 
every shoot of which at the proper season 
affords its bunch of orange-scarlet blooms, 
literally covering the whole space sometimes 
with its fiery blossoms. A south wall should 
be its station, and its leading shoots should be 
supported while the plant is taking up its 
position ; and, as it looks best when allowed 
to ramble or grow outwards, as well as the 
ivy, when it has reached the top, it is as well 
to continue fastening the leading shoots, that 
its own weight may not tear out its natural 
holdfasts, that Avill be insinuated into every 
crevice. The simplest mode of propagating 
the plant is by layers, which may be pegged 
down any time between September and March, 
and not be taken off for twelve months. 
With regard to the pruning, all you have to 
do is to cut back the strong shoots and cut 
away weak ones altogether. The flowers are 
borne on the young shoots of the same season, 
and if the plant is in health every one of the 
shoots will perfect its pannicle of flowers. 
There is hardly a more beautiful object than 
a well-trained plant of this Bignonia from the 
time when it is coming into bloom until it has 
gone off its flowering, for whether partially 
or wholly in blossom, the flowers are so 
striking that a few make a noble show. 
GARDENIA STANLEYANA. 
This is a new stove shrub, of considerable 
beauty; it grows upwards with an erect stem, 
and near the top a series of branches spread 
out, nearly at right angles with it, or perhaps 
rather drooping ; these branches are furnished 
with opposite oval, shining leaves, and from 
the axils of these leaves the flowers are pro- 
duced,- in considerable numbers. The flowers 
are several inches long, and stand erect from 
the horizontal-growing branches ; they consist 
of a long, narrow, rich chocolate-coloured 
tube, and near the extremity widen out like a 
pouch or funnel; the limb, or the spreading 
portion at the extremity, is white, prettily 
mottled and marked with purple ; the margin, 
or edge of the tube, being of a delicate flesh 
colour. It is now (March) in bloom in the 
stove of the Royal Botanic Garden, of Kew ; 
and Sir W. Hooker states, that when in its 
perfection, he knows of no plant more beauti- 
ful. It was brought from Sierra Leone, by 
Mr. Whitfield, who has been engaged in col- 
lecting objects of natural history for the Right 
Honourable the Earl of Derby; and who has 
succeeded in adding several new, and exceed- 
ingly handsome plants, to the collections of 
this country.

England is generally considered to be a

a broad umbrageous canopy of green ; her
