Culture dc. as above. This species 

 flourishes in light sandy or peaty soil, in 

 borders, the edges of shrubberies &c. 

 When seeds ripen in this country, as is 

 sometimes the case in favourable seasons, 

 they may be sovm in cold frames or gentle 

 heat in autumn or spring, the seedlings 

 being pricked off and grown on imder glass 

 until about the end of May, when they 

 may be transferred to the open border. 

 EstabHshed plants should be disturbed 

 only about every third year, when they 

 may be divided in the usual way.
