THE FLORIST’S JOURNAL. 
they are natives, has been very fairly tried in the case of this plant. 
But the China Aster remains just as impatient of frost as it was 
on the first day of its introduction into Europe. As an orna¬ 
mental plant, however, it has been much improved by the German 
florists ; new colours have been obtained, and these have been so 
curiously blended with the original self-colour, that they are 
really very interesting to look at. For the sake of comparison, 
they are best shown in beds, or in a continuous drill, as a boun¬ 
dary to any compartment of the flower-garden. 
Perennial Lupines are also favourite auxiliaries of the flower- 
garden, especially if he wishes to produce any strongly marked 
feature in his arrangement. M.

There are innumerable exotic beauties in the grounds and 
houses of this establishment, and all arranged in the most admi¬ 
rable order. The liberal style in which the whole is conducted, 
the numerous and expensive structures erected for the propagation, 
culture, and preservation of this great and valuable collection, 
reflects the greatest credit upon the judgment and practical skill 
of the proprietor. 
To name every conspicuous object of the vegetable kingdom 
which attracts the notice of a visitor to this interesting depot of 
exotic plants, would occupy many of our pages ; and without 
noticing what is in the conservatories, greenhouses, orchidaceous, 
or other stoves, pits, &c. we shall only on the present occasion 
remark on a most transcendently elegant climber, now, as it has 
been for several months past, in full bloom, in a propagating stove, 
namely, the Ipomcea Learii , so named by Mr. Knight, which is a 
plant as yet but little known in European collections, except those 
which have been sent out by Mr. Knight, the original possessor, 
who received the seed from his own intelligent collector, Mr. 
Lear, from the island of Ceylon. The plant in question is planted 
in a box in one corner of the stove, where it has been about 
twenty months ; and it now covers the trellis under the glass 
roof, nearly over the whole, or at least two-thirds, of the length 
of the building—say twenty feet. The branches produce mime-
