Zone 5b, blooming now.
Morning bloomer - closed by mid-day.
From seeds I scattered this spring.
(I should have a record of it someplace, but??
)
24" stem, unbranched until very close to the blooming end.
Entire plant is gray-green in color.
Blooms are approx. one-half, to 3/4 inch in size.
Leaves look like perennial aster leaves - small and narrow.
Is this a tall annual phlox, perhaps? I had tossed out some seeds of those...
