GARDEN FLOWERS. 223 



ginning of August, the shoots should not be topped, but al- 

 lowed to grow tall for blooming ; or, if stronger spikes of 

 bloom are required, the stopping may be discontinued earlier. 

 The object of stopping is, however, to produce a very bushy 

 plant, that may yield a large number of flowering shoots. 

 There is no difficulty in cultivating the plant, which, when 

 established, should be grown in rich loam. With this, and 

 other similar free-growing plants, it is better to raise young 

 ones annually than to attempt to prune back or otherwise 

 renovate the old specimens, which are chiefly to be pre- 

 served to furnish cuttings in the spring.
