Cult. Malachra is a genus of plants destitute of beauty, 

 therefore not worth cultivating, except in botanic gardens. They 

 only require to be sown in the spring in pots filled with loam 

 and sand, and placed in a hot-bed, where they may remain until 

 they have ripened their seed, or they may be removed to a 

 stove when of sufficient size. They should be planted separately.
