The numerous hybrid varieties of this genus are among 

 the most beautiful foliage plants we have. The original 

 seed parents appear to have been Blumei and C. Verschaf- 

 feltii, one of the first with highly coloured foliage (this is 

 now used extensively for summer bedding), later on a 

 large number of beautiful varieties were raised at the 

 Chiswick gardens of the Royal Horticultural Society, 

 and since then many others have been added. In later 

 years seed selected from the best has proved an easy 

 means of getting good varieties. Sown in February good 

 plants may soon be established by June, and a selection 

 of the best made for growing. They are also readily 

 propagated from cuttings. Short tops should be taken 

 and put in light, sandy compost, the finer varieties are 

 not so hardy as Verschaffeltii, and are difficult to keep 

 through the winter unless a temperature of 60 can be 

 sustained, but they will do well in an ordinary green- 



house during summer. Pot in a compost of loam, leaf- 

 mould, with some manure, and sand.
