Sylphium mohrii.  Mohr’s Rosinweed.  An endangered plant of the American South (Georgia, Alabama, Tennessee).  These are 2nd year seed grown.  Apparently hardy beyond the south.  A hairy plant to 6ft tall.  Multibranching, sunflower-like blooms from late July into September is what you get, in a soft shade of yellow that is rare indeed in late summer.  A valuable plant for the back of the garden, less imposing and of a more desirable shade than the more commonly grown Sylphium perfoliatum.
