cate shoots on a wire trellis, or small twigs of branches stuck 

 in the pots. T. tricolorhm, T. tricolorum superbujn, and

Yerhena. 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 color, from 

 the richest scarlet to the purest white, and, in addition to 

 the beauty and profusion of their flowers, several of them

 V. hicolor grandiflora^ scarlet crimson eye. Y. Blue. Queen, 

 fine blue; F. Beauty, rose; Y. Feastti, large, white fiiding to 

 lilac ; F. Beauty supreme, beautiful large rose ; F. Mestonii, 

 bright scarlet; F. Queen, pure white; F Polkii, very dark

 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, v/ill root in a few weeks. The whole family
