VINES FOR THE COOL HOUSE iy i 
a trellis eight or ten inches away from the end or 
back wall of a house. They require very little 
pruning, but should be kept sprayed and liberally 
fed if the flowering season is to be prolonged. 
They are splendid subjects for training over 
small trellises, especially as veranda decorations, 
where their sweet odour is always an added attrac- 
tion. The best form is the Arabian Jasminum 
(Jasminum Sambac) which will produce its 
white flowers the year round if properly fed. 
It requires a rather warm house; 60° will do but 
65° is better. A good winter-flowering type 
is J. Gracillimum, which should not be dried off 
until after it has borne its clusters of white blooms. 
An exquisite old favourite is the “‘sweet jessa- 
mine”? of poetry (/. officinale) that bears in 
summer small clusters of white, sweetly fra- 
grant flowers. And yet an improved form, with 
the same fragrance but larger flowers is /. offi- 
cinale var. affine. The most fragrant of all is 
the Royal, Catalonian, Italian, or Spanish jas- 
mine (/. grandiflorum) also white-flowered, which 
is used extensively in making perfume. The 
best yellow-flowered type is the Italian Yellow 
jasmine (J. humile) that blossoms in late summer. 
A plant suited to cool house cultivation, but 
especially interesting because of its association
