THE PASSION-FLOWER.

are some, and these the majority, which 
require to he cultivated in the temperature of 
the stove ; others succeed to perfection in a 
green-house ; and P. ccerulea, and some of its 
varieties, are sufficiently hardy to be cultivated 
against a wall, in the open air. 
The natural habit of the whole race of 
Passion-flowers, is that of strong, vigorous- 
growing climbers ; and hence they are none of 
them very suitable for growing in pots. When- 
ever this natural tendency to extend them- 
selves is to any extent interfered with, the 
production of flowers is, in a great measure, 
prevented, owing to the expenditure of the 
organized sap in the formation of other leaves, 
to prepare the materials necessary to the 
formation of flowers ; and, on this account, it 
is only one or two of the most free-blooming 
kinds which can be successfully treated under 
pot culture. 
It would be altogether outstepping our 
limits, to attempt to describe, or even to 
enumerate, all the kinds which exist in our 
gardens ; and we think it will be sufficient for 
our purpose to describe, somewhat more in 
detail, a selection of some of the more dis- 
tinct and handsome species at present known. 
This will be the most useful course we can 
adopt. 
Passijlora coertilea. 
SELECT LIST. 
HARDY SPECIES. 
Passiflora ccerulea, (Common blue Pas- 
sion-flower.) — This is the only showy hardy spe- 
cies which is at present known. There are one 
or two others nearly hardy, but they produce 
very insignificant flowers. Of P. ccerulea 
there are Ave cultivated varieties, slightly dif- 
fering from the original kind. It has five- 
lobed leaves ; and the flowers are pale 
greenish white ; the filaments of the ray are 
purple at the base, white in the middle, and 
blue at the tips. The plant will extend over 
a considerable space, and flowers freely. It 
should be planted against a wall, where it 
will stand our ordinary winters, with no other 
injury than having the points of the shoots 
killed. 
GREEN-IIOUSE species. 
Tacsonia (or Passiflora) pixnatisti- 
pula, (Pinnate stipuled Tasconia.) — This is 
a very free-growing plant, which probably, 
in some situations, might be found to be hardy, 
as it inhabits a colder climate than P. ccerulea. 
The stem is downy ; the leaves of three 
narrow lobes; the calyx of the flowers is 
nearly white, the petals rose-coloured, and 
the filaments of the ray blue. The genus 
Tasconia differs from Passiflora, among other 
things, in the long tube of the flowers. 
P. incarnata, (Flesh-coloured Passion- 
flower.) — This has three-lobed leaves, pink 
flowers, and the filaments of the ray in a 
double circle, and of a purplish colour. Per- 
haps this can hardly be considered a green- 
house species. 
stove species. 
The greater number of the Passion-flowers, 
and all the more handsome kinds, require a 
greater degree of warmth than is obtained 
in a green-house. They do not, however, 
require a very high temperature; something 
intermediate between a stove and a green- 
house is most suitable for them ; a house with 
a mean of from 55° to 60° of artificial heat 
would suit them well, except for the matura- 
tion of fruit, which requires a rather higher 
temperature. 
P. alata, (Wing-stemmed Passion-flower.) 
— A very handsome species, with glabrous, 
ovate acute leaves, and sweet-scented flowers; 
the upper side of the calyx and petals is of a 
deep crimson; and the filaments of the ray 
variegated with purple, white, and crimson. 
P. PHCENiCEA, (Phccnicean Passion-flower.) 
— This species somewhat resembles the last, 
but it has much more gorgeous flowers. 
There is a plant cultivated under the name of 
P. elegans, which seems to be a variety of 
this kind, or is, perhaps, the same. 
P. alata-ccerulea, (Hybrid-winged Pas- 
sion-flower.) — This is a hybrid from seeds of 
P. alata, fertilized with P. ccerulea. The 
leaves are three-lobed; the outer side of the 
calyx is rose-coloured, and the inner side of 
the petals is white ; the filaments of the ray 
are variegated with black, blue, and white.
