DAHLIAS FOR FORMING DWARF MASSES.

in pots was, to enable them to be taken up in the autumn and removed under 
shelter, that they might perfect any seeds not come to maturity, at the sign 
of approaching frosts. The plants so operated upon were of rather small 
dimensions, and full of vigour ; they were taken off the wall with considerable 
facility, and being fastened to suitable trellises, not only when placed in a warm 
temperature ripened their seeds as it was desired they should, but bloomed for an 
unexpected length of time. Older plants of I. rubro-carulea, planted in the open 
ground, ripened abundance of seed in the situation in which they grew. 
The knowledge the facts above detailed put us in possession of, is that Pharbitis 
Learii, and Iponuea rubro-ccerulea, are certain to succeed, at least on a conservative 
wall, and not there only, but on any wall or fence enjoying a south or southern aspect. 
Some preparation of the soil in which they are to grow will be necessary. It is 
requisite that it be rather light, not too rich, and the situation, if not naturally dry, 
should be rendered so by draining, &c. Numerous other stove and greenhouse 
climbers suggest themselves as being equally certain to succeed, under similar 
circumstances ; among them the lovely Pharbitis tyrianthina, sl species flourishing 
and flowering beautifully in the greenhouse, although usually regarded as requiring 
a stove ; Convolvulus pentanthus, charming in the extreme when flowering in any 
position, but enchanting if planted where it can grow and flower in a natural 
manner ; and a great number of other fine plants, too numerous to mention here. 
To some of them we may recur at a future opportunity. 
Many dwelling-houses, with a garden adjoining, possess an aspect in which the 
foregoing plants would thrive admirably. Any such, with their walls already occupied 
with climbing Roses, Clematis, &c, present no obstacle to such plants being grown 
against them, as they would, proper provision being made for their roots, without 
doubt, grow and flower in a very pleasing manner, and attaching themselves to the more 
robust living supports, produce a very natural effect. 
The practice of growing Ipomcea rubro-cmulea in pots, and plunging them in a 
suitable situation in the open air, till they become fructiferous, and then removing 
them under the shelter of glass, to display their bloom, suggests the idea of dealing 
with many climbers similarly, some of which may be difficult to flower ; which diffi- 
culty by such means might be overcome. We recommend this suggestion to the 
attention of our readers, none of whom, we feel convinced, will consider we have 
gone too much into detail, or devoted too much space to our present paper, treating, 
as it does, of plants almost unequalled for the splendour of their flowers.
