Bourbons. And then what a pretty little bed of cherry-coloured 
roses of moderate growth may be made with Comice de Seine et 
Marne and Souvenir de Dumont d’Urville. And now for “ couleur 
de Rose,” last, but not least, how profusely in autumn are the fol¬ 
lowing varieties covered with their large and finely shaped rosy-tinted 
flowers, Emile Courtier, Edouard Desfosses, La Gracieuse, and 
Madame Marget, of nearly uniform growth, not tall, not dwarf, they 
are the “juste milieu” among Bourbon Roses, and ought to have a 
very large bed devoted to their beauteous selves.

ON THE CULTURE AND TREATMENT OF THE 
TROPJELUM TRICOLORUM. 
This elegant plant is a native of South America, and is amongst the 
most beautiful of the greenhouse climbers. Those who have never 
seen it growing, would scarcely believe that the thread-like stem could 
support such a profusion of flowers. 
It is a bulbous root, and requires no art to grow it; it is easily 
propagated by cuttings, placed in a gentle heat under a bell-glass, 
care being taken to shade from the sun, and to wipe the moisture 
from the glass once or twice a-day, to prevent them damping off. 
It is also propagated from seed, which sow as soon as ripe; it will 
vegetate sooner by being soaked in warm water several hours before 
it is sown. I have known seed remain in the soil for years before it 
vegetated; care must therefore be taken when a plant makes its 
appearance, that it is taken up carefully without disturbing the rest 
of the seed, and the sooner it is removed the better. It has also the 
singular habit of occasionally striking down to the bottom of the pot, 
and forming the bulb amongst the drainage, and then turning up¬ 
wards and making its appearance above the soil. It will bloom the 
first season, but abundantly the second. Sometimes the old bulb 
will remain dormant for a season. Grow it in rich soil, with a good 
proportion of old manure, a sufficient quantity of Calais sand to make 
it light, and a little charcoal; some prefer peat and loam. For cut¬ 
tings, use simply soil, with a good proportion of sand. The plants 
will continue in bloom for several months; and when they have done 
flowering discontinue watering, and the bulbs will soon be in repose. 
Then place the pots in a dry situation, till the time arrives for 
the bulb to vegetate, then re-pot it as previously directed; and, as a 
general rule, never pot any plant without plenty of drainage ; pieces 
of broken pots will answer this purpose admirably. 
No lady that is fond of plants should be without this beautiful 
little gem in her collection,—or The Florist upon her drawing-room 
table.
