Leia'nthus longifo^lius. This is a plant of a rather loose but elegant habit, and seems to 
flower freely. The blossoms hang down from the lateral shoots like those of the axillary flowered 
Fuchsias, and are yellow, with a slight tinge of green. It is very like the L. nigrescens in habit, 
and makes a good contrast with it in the colour of the flowers. 
Phlo'x Drummondii, varieties. The varieties of this beautiful half-hardy annual are 
amongst the gayest ornaments of the pleasure-ground in the summer season. From their rapid 
spreading growth they are well suited for adorning the raised mounds upon which Coniferse and 
other trees are planted in the arboretum, or for the small circles round standard shrubs on a 
lawn. Mr. Cole, of Blackheath Park, exhibited some handsome varieties at the meeting in 
Regent Street ; amongst them was a streaked or mottled one, which if constantly so, well deserves 
notice, and a variety with flowers almost white, with a rose-coloured eye in the centre, in which 
respect it is superior to the white one noticed last month at Mr. Grooms'. Mr. Grooms' flower, 
however, is a more decided white, produces itself from seed with certainty, and has broader 
foliage. At Messrs. Knight and Perry's Nursery there is a profuse variety of these flowers 
raised from American seeds. 
OPERATIONS FOR SEPTEMBER. 
Although the garden has yet scarcely reached the zenith of its autumnal beauty, the season 
is fast approaching, especially in the northern and colder districts, when its chief ornaments will 
be destroyed by frost. Even this month, in some localities, is not exempt from the liability ; 
hence, not only must every exertion be put forth to keep the utmost neatness whilst the flowers 
last, but active preparations must be made for securing an abundant supply of plants for a 
succeeding season. All those numerous species of tender plants with which our borders are now 
principally adorned must be propagated without delay, for the earlier cuttings are procured and 
rooted, the more likely they will be to stand the winter well. In places where the number 
required is very extensive, a decaying hotbed with about two or three inches of sand or fine 
sandy earth laid on the top, and covered with a frame and glass lights, will perhaps be better 
than pots, and will certainly prove a great saving both of time and room. Some of the metro- 
politan cultivators manage to keep their whole stock of Calceolarias, Verbenas, Petunias, &c, 
in this way through the winter without potting ; but there is less risk of losing them when they 
are planted by threes, in pots of a suitable size, to allow the roots to fill them before November. 
In order to produce a sufficiency of roots it is of course necessary to keep the young stock in 
a growing state for some time after they are potted out ; and it is important that this growth 
should cease or nearly so, and the shoots be somewhat hardened whilst the sun has power to 
do it, so that they may require less protection from cold, and less attendance in the winter 
months. The formation of many roots is more to be desired and promoted now, so far as art 
can do so, than the production of an increased stem and foliage. To this end, therefore, the 
young plants should be potted in a poor soil, such as peat and sand, which will cause them to 
protrude a great number of fibrils, without causing much development of stem. A rich soil, 
on the contrary, produces great luxuriance in the leaves and shoots, without the emanation 
of a corresponding multiplicity of rootlets — a state the very opposite of that we ought to 
strive for. 
Scarlet Pelargoniums and other things of a like succulent nature that are employed in large 
quantity for the flower-garden, on account of their liability to rot, should never be left in frames 
or pits through the winter, unless there is some heating apparatus which, in conjunction with a 
judicious ventilation, is capable of preserving a dry atmosphere. Consequently, it will be 
advisable to plant cuttings of these plants at once in pots or in large flat pans, so that they may 
require no re-potting, and be easily removed when rooted to some dry shelf in a greenhouse. 
If there is no other convenience for their conservation than common frames, the pots should be 
set on raised stages, instead of being plunged in ashes : the frames, moreover, should be stationed 
in some dry, airy spot. 
In taking cuttings, too much care cannot be bestowed on keeping the different coloured
