I'm told that our house sits on what used to be farmland not more than a generation ago, and mullein (Verbascum thapsis; common mullein, wooly mullein, flannel plant...you get the idea) is a farm weed that shows up here and there every season. I'm fond of this weed. The leaves are softer and silkier than lamb's ear (but to describe them as "a kind of Native American Charmin"? Eeuuww).
Mullein in the wrong place at the wrong time is gangly, ugly, and yes, weedy. But sometimes it just shows up where, it turns out, it needed to be. This summer, it's next to the David Austin rose 'Graham Thomas', punching up the yellows in a mostly bronze-leaved bed, and helpfully obscuring the rose foliage that's already tattered and pitted with blackspot.
Last summer, it added heft and textural contrast to the agastaches and penstemons:
In the early days of this garden, I sought out and planted the verbascum 'Helen Johnson', enthralled by the description that I'd read in Jamaica Kincaid's garden book. Her delicate buds were pretty, her dusky peach-salmon color unusual, and she didn't last more than one season. I think I'll stick to the great mullein, and look forward to its surprises in the seasons to come.
