Verbascum phoeniceum "Violetta" (Nettle-leaved Mullein)
I am partial to all Verbascum (Mullein), particularly Verbascum phoeniceum "Violetta." Its blooms are a striking shade of violet/purple, and it couldn't be easier to grow. "Violetta" isn't a bit fussy about water; it's deer and snail proof; it's agreeable to sun or bright shade; and it blooms from late spring through early summer. The flowers of Verbascum "Violetta" begin opening at the bottom of the stem and work their way up, and if cut back, it is a repeat bloomer, but you will want to let some seeds develop for re-seeding. As with most Mullein varieties, the dark green foliage is also an asset, forming attractive, flat rosettes. This stunning Verbascum grows to about 30 inches in Zones 5-10. Quarts.
