A native of California, whence seeds have been recently 

 sent to the Horticultural Society. It forms a handsome 

 hardy perennial, flowering in great profusion from May to 

 September. 



In some respects this is even a better species for Gar- 

 dens than L. polyphyllus ; for, if less stately, it is more gay 

 "i Us appearance, and a longer flowerer. The diversity of 

 colours in the petals no doubt contributes very much to this 

 effect, which is increased by its loose, but not straggling, 

 mode of growth.
