Cult. The species are mostly weedy and not worth culti- 

 vating for ornament, and therefore they are only fit for the 

 arrangements in botanic gardens. Those species belonging to 



sections Carddminum and Brachylobos, require a moist soil, 

 some will require to be planted in water. The annual species 

 may be sown in the open borders early in the spring. The rest 

 will grow under any circumstances.
