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.
