A WOW! plant.  Large black-purple flower heads emerge on the black-purple stocks in mid-summer.  A major bee attraction and a plant that adds drama and elegance to the garden.  Biennial, blooms in its second year from seed.  Zone 4-10.  Sun to Part Shade.  4'-6' tall.   Seed germinates best if sown fresh ...  in the fall to benefit from winter cold, otherwise will require cold stratification in a refrigerator.    20 seeds.
