Cult. The greater part of this genus of succulent plants 

 being biennial, the seeds of them should be sown in spring or 

 summer, in pots fiUed with gravelly sand and loam, well drained 

 in the bottom. Cuttings of them are also easily rooted, if laid 

 to dry a few days after they are cut, before being planted, espe- 

 cially of those species which are permanent. Brick rubbish, 

 mixed with loam, is a good soil for the grown up plants.
