256 GREEN-HOUSE — REPOTTING. [March. 
in the pots. T. tricolorum, T. tricolorum superbum, and T. 
pentaphylhnn have beautiful scarlet flowers marked with yel- 
low and black, and are superb and lovely when in bloom. T. 
brachyseras has yellow flowers. (Soil No. 10.) 
Verbena. The beauty of the green-house in spring and 
the flower-garden in summer is greatly augmented by the 
late introduction of this lovely family of perpetual flowering 
plants. There are among them every shade of colour, from 
the richest scarlet to the purest white, and, in addition to 
the beauty and profusion of their flowers, several of them are 
exquisitely scented. V. chamsedry folia, or melindres, was 
the first scarlet species introduced, and it is yet pretty. V. 
bicolor grandijiora, scarlet crimson eye ; V. Beauty, rose ; 
V. Beauty supreme, beautiful large rose; V. Polkii, very 
dark purple crimson; V. Nymph, beautiful pink; V. Tri- 
umph, very dark crimson ; V. Eclipse, striped; V. Heroine, 
blue, dark centre ; V. la Gracious, clouded blue and lilac ; 
V. Queen of the Bay, white, deep crimson edge; V. Star of 
the West, scarlet, pale eye ; V. St. Marguerite, shaded scarlet 
crimson ; V. Iphogcne, lilac, marbled with blue and purple ; 
V. Wonderful, rose-white, pink eye; V. White Perfection, 
pure white. 
Robeson's Defiance, the best scarlet; Buist's Perfection, 
the best sweet-scented lilac. 
These are principally new varieties, of perfect formation ; 
the flowers in many are as large as a clime, far outvieing 
those cultivated a few years ago. It is only twelve years 
since I grew the first white, pink and crimson verbena, from 
seed received from Buenos Ayres. They created a very great 
excitement in the floral world, both in this country and 
Europe. Now there are thousands produced from seed an- 
nually. In England, they bear the titled name of Ladies, 
Marquesses and Queens, commanding a very high price ; but 
with all their titles, none of them excel a few of those named 
above. They require very little water during winter, and 
should be kept on a dry airy shelf till February, when the 
pots may be enlarged except those intended for the garden, 
which can be planted out about the middle of April. Cut- 
tings of the young shoots, placed in sandy soil and covered 
with a glass, will root in a few weeks. The whole family 
should be industriously collected and cultivated ; for truly we 
arc not acquainted with a tribe of plants that will give as much 
satisfaction with as little cost and trouble : they naturally
