March,'] GREEN-HOUSE — REPOTTING. 229 



Edinburgh^ where there are two large houses devoted to their 

 culture ; and through the whole year a continued profusion 

 of bloom is kept up. Some of the plants are eight feet in 

 diameter and fourteen feet high. The soil used is a coarse 

 sandy peat. Pots drained with potshreds, and pieces of free- 

 stone are put down the sides of the large pots and tubs ; where 

 these can be had they are essential to the culture of mount- 

 ainous plants, preventing them from being saturated with 

 moisture, or from becoming dry, thus keeping the roots in a 

 medium state; for if once the roots are allowed to get tho- 

 roughly dried, no art of the gardener can recover them . This 

 may be the true reason why they are said to be difficult of 

 cultivation. 



In the summer season, the pots must be kept out of the 

 violent sun, for in a few hours the pot would become heated, 

 dry the roots, and cause death, or a brownness of foliage 

 which would never again become natural. In winter, too, 

 much fire heat will also hurt them. They only require to 

 be kept free from frost, need a great deal of air, and plenty 

 of light ; consequently, should be placed near the glass, that 

 they may have the benefit of all the air that is admitted. 

 Their flowers are as varied in shape as variety or color, but 

 they all partake of a wax-like nature, and are very persistent. 

 (Soil No. 5 for young plants : when older. No. 6 will do 

 better.) 



The finest and most select varieties that appear to with- 

 stand the severity of the summer are the following : —
