This is one of my new favorite plants: "sweet everlasting", a.k.a. the awful mouthful "Pseudognaphalium obtusifolium". It is an understated little white annual or biennial - meaning sometimes it will flower and die in its first year, and sometimes in its second - and it is native to my area.
I'm not sure that I have seen this flower growing anywhere except as a weed in neglected places. This surprises me, because it blooms at the tail end of Autumn when most everything else is slumping from frost damage or looking like a ragged seedy mess. And when these guys go to seed, they don't look any different from the flower: they remain covered in little white buds up until the wind blows them apart in loose dry bits. They would be excellent for dried flower arrangements, if I cared for such things.
Not only was this a bright spot on the cold slide into winter, but this one volunteered itself in a part of my lawn that I am experimentally trying to turn into meadow. And here I didn't think there would be anything to report in the meadow department until next season!
*I find that the stress generated by Christmas buildup and the lack of sunlight is best countered by a reduction in extra-curricular projects this time of year.
