36 THE FLORIST. 
flower-garden and parterre, and as it is of the easiest culture, growing 
_well in any moderately rich garden soil, will soon become a popular 
plant, destined to throw its progenitor out of notice. This variety has 
been raised by the Messrs. Carter, of Holborn, and is the result of a 
very careful selection of the best varieties only for seed from year to 
year, added to a high state of cultivation. 
Nigella hispanica alba.—tThis is a new variety of Nigella, of free 
growth, compact habit, with flowers of a pure white; it will be found 
extremely useful for many purposes in the flower garden. This variety 
was recommended by the Horticultural Society, 
Ipomea limbata elegantissima.—The Ipomea is well known as fur- 
nishing the most graceful and charming of climbing plants. The exotic 
species, as Learii, Horsfallii, and rubro-ccerulea, are known as conser- 
vatory climbers of great beauty ; several others of this family are hardy 
enough for out-door decoration during summer, and trained to a south 
wall few plants are so beautiful. The blooms, though of short duration, 
are produced in great profusion, and during the mornings display a rich 
mass of colour, comprising every shade of violet, blue and white, while 
their graceful habit adds not a little to the admiration in which they are 
held. Our present subject is a new variety, raised from I. limbata, 
from which it differs in having a star-shaped spot of intense blue, sur- 
rounded with pure white, making a beautiful contrast. Although the 
roof of a greenhouse would certainly be most suitable for this elegant 
plant, yet we mean ourselves, and advise all who have the room, to try 
it against a south wall. For this purpose the seeds should be sown 
early, and potted off and grown in a frame until one foot or more high, 
when they will require being gradually hardened off by placing them in 
a greenhouse temperature. Towards the middle of May they should be 
carefully transferred from the pots to a well-prepared compost and 
planted against a south wall, sheltering them for a time by placing 
a spare light or two before them until they fairly begin to move; after 
which they will require constant watching to direct the shoots regularly 
over the trellis, which should be provided for them, in preference to 
nailing them against the wall; round the wires of a trellis they will 
naturally twine themselves, and unfold their blooms more gracefully 
than when nailed. ‘This fine variety has also been obtained by the 
Messrs, Carter, through their agent on the Continent, and has resulted 
from a careful hybridising of I. limbata. We hope soon to see our 
garden walls and trellises covered with these charming exotic-looking 
plants, for which they are particularly adapted ; and as the hybrids now 
produced are much hardier than the older species, we see no reason 
why they should not become as common as the Convolvulus major. 
We beg to tender our best thanks to the Messrs. Carter, for allowing 
us the opportunity of figuring our present subjects. }
