| There is a series of "English" violas that are noticeably fragrant, that includes cultivars named "Etain" (yellow with lilac edge) and "Columbine" (white striped lilac). I find Columbine highly fragrant -- it's a perennial, though not tremendously vigorous. I notice that it is widely available this year and have purchased a few. |
