Cult. None of the species of Urena are worth cultivating 

 unless in botanic gardens, except U. speciosa. They are plants 

 of easy culture, will thrive best in a mixture of loam and peat, 

 and cuttings will root readily if planted in the same kind of soil, 

 under a hand-glass, but this in most cases will be unnecessary, 

 as most of the species ripen seed in plenty.
