Camellias are 

 amongst the most

 are either double or 

 single, but the first 

 are the better known. 

 Grow in peat and 

 sand, with the addi-

 at this period, not 



allowing the plants to become either dry or very wet; care-

 of the young wood in June and July, in a cool frame. The 

 -doubles are best grafted or inarched on these ; graft at any 

 time during winter in the warm pit, and continue to grow in the 

 same for a time after union has taken place. Inarching should
