in the possession of several cultivators for some time past, has not, we believe, be- 
fore flowered in the vicinity of London. It has recently been the subject of much 
conjecture, and the popular opinion has been, from its general habits, that it would 
produce flowers of an expanding- nature, but this has happily proved to be un- 
founded; it is now flowering in unbounded profusion at the above nursery, and the 
flowers are produced at the axil of every leaf on a footstalk of six or eight inches 
in length ; the calyx is of a deep red colour, the petals yellow, with small black 
stripes, and the flowers are something similar to those of T. tricolorum ; the 
foliage is large and handsome, the plant a most luxuriant grower and abun- 
dant flowerer ; the flowers extremely beautiful, and it is highly worthy of a place 
in every collection. Impatiens scapiflora. This is an extremely pretty new stove 
plant ; the flowers are of a delicate lilac colour, and are produced on a flower-stalk 
about six inches in height, which, with the leaves, springs from the root ; it has a 
most elegant appearance, and has never, we believe, before flowered in England. 
Physostegia truncata. This is a new and very pretty hardy herbaceous plant, and 
is now beautifully in flower at the above nursery ; the flowers are of a delicate rose, 
or flesh colour, prettily spotted with brownish red in the inside of the corolla; 
they are produced on a flower-stalk, about eighteen inches in height, after the 
manner of the species of Dracocephalum, to which this genus closely approxi-. 
mates, and is nearly allied.

On a method of arranging Greenhouse Plants in the open air during the 
summer season. 
The usual treatment given to such plants as will not endure the winter of our 
climates, and do not require the temperature of the stove (commonly designated 
greenhouse plants), being to remove them during the summer months from the 
greenhouse or conservatory, and place them in the open air, it becomes desirable 
that they should there be arranged in such a manner as shall tend most to render 
them an object of ornament, and offer facilities for watering and otherwise attending 
to them ; the latter of these objects is pretty generally attended to, but the former 
is seldom taken into consideration ; hence we usually see them arranged in long 
beds or masses, which generally have an extremely heavy and dull, as well as 
formal appearance ; to obviate this, we propose laying before our readers the 
system pursued by Mr. Knight, Chelsea, and we are sure that any one who 
sees it cannot fail to be struck with the peculiar neatness and beauty of the 
appearance of his greenhouse plants during the summer season.
