Cult. The perennial species of this genus thrive best in a 

 light rich soil, and they require to be frequently transplanted 

 and divided, otherwise they will not long exist, particularly the 

 double varieties of Hesperis matronalis ; the best time to do 

 this, is after they are done flowering and are again beginning to 

 spring afresh from the root. The biennial and annual sorts do 

 well in any common garden-soil, requiring the same treatment 

 as other hardy annuals and biennials.

Cult. These plants are scarcely worth cultivating, except in 

 botanic gardens. They only require to be sown in the open 

 ground, and treated like other hardy annuals. A light sandy 

 soil will suit them best. 



LVII. SISY'MBRIUM (St<ru/i/3ptov was the Greek name of 

 some aquatic plant. It appears to have had an agreeable smell. 

 Ovid advises that Venus should be propitiated with garlands of 

 myrtle, of roses, and of sisymbrium. It is, however, more pro- 

 bably derived from aimftoy, sisibos, a fringe, as some of the 

 species have fringed roots). All. ped. 1. p. 274. B.C. syst.
