Cult, Pretty little plants, native of marshes and bogs. The 

 species grow best in a mixture of peat and sand, and the pots in 

 which they are grown should be kept in pans of water. The greater 

 part are annuals, and even those called shrubby will not survive 

 more than a season in our stoves ; therefore they are all to be 

 increased by seeds. The seeds should be sown in pots tilled 

 with the same kind of mould recommended for the plants, placing 

 them in a hot-bed, where they should be kept rather moist ; and 

 when the plants are coming into flower they should be removed 

 from the hot-bed to shelves in the stove.
