SEMPERVIVUM. (HOUSELEEK.) 

 A large genus of hardy or greenhouse herbs or 

 sub - shrubs (<ird. Crassulaoeaj) with succulent 

 leaves, which adapt them to living in the most 

 arid situations. The hardy species are suitable 

 for edgings, rockwork, old walls, and roofs, while 

 some of the greenhouse species make interesting 

 pot plants for the window or tor bedding in 

 summer. The nomenclature of the genus is in a 

 confused state in gardens on account of the 

 difficulty of determining many of the species. 

 Propagation, by seeds sown under glass in spring, 

 or by offsets. Sandy soil, with a little old mortar 

 or lime rubbish. They flower best in full sun.

SENECIO. (RAGWEED, GROUNDSEL.) 



A very large genus of annual, biennial, or peren- 

 nial stove, greenhouse, or hardy plants (ord. Com- 

 posite), of herbaceous, sub-shrubby, or shrubby 

 habit. Many of the plants called by botanists 

 Senecios have other garden names, whicli are used 

 in this work, and only a small number of the many 

 true Senecios of gardens can be given here. Prop- 

 agation, the annuals by seeds ; the perennials by 

 seeds, division, or cuttings. Any common soil of a 

 loamy nature. (See also CiNEHARiA, KLEINIA, 

 and LIGULAEIA.)
