Verbascum chaixii album (Mullein)
I am smitten with this white-flowering perennial Mullein, Verbascum chaixii album. Its spires are jam-packed, from top to bottom, with small flowers the color of fresh cream with centers of orange and purple. Just as much as the profusion of flowers on this attractive Mullein, I like its large, textured rosettes of foliage, not to mention the architectural aspect it lends to my garden. I have heard some call Verbascum invasive, but for as many years as I have grown it, I have only two or three extras from reseeding - just not enough, if you ask me. This Mullein is easy to please, and if you cut it back after blooming, it will send up new spires and will re-bloom. Growing from two to four feet, Verbascum chaixii album prefers sun and well-drained soil in Zones 5-10. Quarts.
