THE GREEN-HOUSE.

Convolvulus canariemis, B. M. 1228, is a herba- 

 ceous plant with a twining stem, and very showy 

 reddish blue and white flowers which appear in July. 



Jasminum grandiflorumy B. R. 91, has a fine

 rous flowers, and merits a place next to the two last 

 genera. 



A soil composed of loam and sand, with a little peat 

 earth, will suit all these plants. It must be well 

 drained by a bed of gravel or rubbish below, as from 

 the water which drops from the plants in pots on the 

 stage, and that used to syringe the house, or to wash 

 the pots, climbers are very apt to be overwatered, 

 and the earth to become sodden ; and when this is 

 the case, they cease to thrive.
