Verbascum bombyciferum ‘Arctic Summer’ (‘Polarsommer’)
Large group of rosette-forming, summer-blooming plants that send up spikes closely set with nearly flat, five-petaled, circular flowers about an inch across. Both foliage and stems are often covered in woolly hairs. Taller mulleins make striking vertical accents.
Grow all in well-drained soil. Cut off spent flowers to encourage a second round of blooming. Mulleins self-sow freely—and some are downright weedy, such as the attractive roadside weed V. thapsus.Verbascum bombyciferum ‘Arctic Summer’ (‘Polarsommer’)
