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.
