VERBASCUM 



smaller than in V. phlomoides. The plant has the dis- 

 advantase of being seusitire to wetness, its soft, 

 woolly Ivs. damping off in wet situations over winter. 



V phlomoides. though less popular than the preced- 

 ing, is probably the best of all the yellow-fld. species. 

 It has the advantage over 

 V. Otympicum of being a 

 ' true biennial of easier cul- 



ture with larger fls. and a 

 longer season of bloom, 8- 

 10 weeks, and even then if 

 cut half way down it will 

 throw out lateral bloom in 

 late autumn.
