Cult. All the species of this genus are truly ornamental 

 when in blossom. The hardy herbaceous kinds thrive and 

 flower best in light rich earth or peat soil ; but in winter most of 

 the kinds require to be protected by planting them in pots and 

 placing them in a frame or green-house. They increase freely 

 by the suckers from the roots or by seed. The green-house 

 and stove perennial herbaceous kinds grow well in a mixture of 

 peat and sand, and are easily increased by dividing, and by seeds. 

 The shrubby, stove, and greenhouse kinds grow well in the 

 same kind of soil recommended for the perennial herbaceous 

 species, and are easily increased by cuttings in the same kind 

 of soil. The seeds of annual species require only to be sown 

 where they are intended to remain.
