 p. ;}09.) A native of the south of Germany, Switzerland, France, and 

 Spain; and introduced in 1817. It is a trailing plant, growing to about 

 1 ft. in height, and producing its pale yellow flowers in June and July. 

 Sweet says that it is covered with flowers during a great part of the summer. 

 After flowering, most of its leaves become quite silvery on both sides. It 

 requires very little protection. Plants were in the Chelsea Botanic Garden, 

 raised from seeds received from Germany, in 1828.
