454 On the Culture of the Passiflora. 
They appear to me, to prosper best in a good rich loam mixed with 
one-half leaf-mould. They require a considerable quantity of water 
whilst in a growing state ; and it is necessary to attend to training the 
branches as they grow, or they soon become entangled, and in loosening 
them, not unfrequently either tendrils or branches are broken. 
There are not many green-house species, although the P. incarndta, 
P. palmdta, P. idulis, P. maculdta, . and P. Chinensis, will do very 
well in it ; as also some excellent hybrids, which are very free flowerers, 
as P. rilbra. P. cosrilleo-racemdsa, P. angustifolia, and P. Colvilliij, 
all of which, are of easy culture, and highly ornamental in a conserva- 
tory ; and if they have plenty of room, they will flower nearly all the 
year round. 
If they are to be grown in a common green-house, I would plant 
them for the roots to grow under the path-way, as I recommended for 
those in the stove. I conceive, a gardener cannot introduce a better 
plant for climbing up small painted ^ires. 
Some of the more hardy-growing sorts would do for a vinery, and 
when the lights were taken off in the winter, the branches might be cut 
in, and the whole plants matted up until the commencement of forcing 
again. 
If none of your more able correpon dents take up the matter, I will 
try to comply with the request of T. H., respecting the culture of greenr 
house plants. ♦ 
Should these hasty lines be thought worthy of notice, I shall feel 
obliged by their insertion. 
I am. Gentlemen, yours, respectfully,
