Cult. None of the species of this genus are worth cultivat- 

 ing unless in botanical gardens. The seeds of the hardy annual 

 kinds only require to be sown in the open border in spring. The 

 hardy perennial kinds are easily increased by dividing the plants 

 at the root or by seeds. Those natives of the Cape are perhaps 

 shrubby ; if this be the case, they may be propagated by young 

 cuttings planted in sand under a hand-glass. All the species 

 grow best in a light sandy soil.
