Vernonia is known for having intense purple flowers! The leaves appear to be acuminate with pinnate-arcuate leaf venation. The leaves for your morning glory appear to be cordate with pinnate venation.
I am glad you identified and posted Rudbeckia triloba (Thin-leaved coneflower). I’ve seen many growing along the edges of fields on my way home. The leaves appear to be ovate to lanceolate in shape and some entire (smooth) margins and some serrate (toothed) margins.
Gorgeous morning glory! It appears that there are 5 fused or nearly fused petals. Though the base of each leaf is cordate, the apex of each leaf is acuminate. How did these introduced flowers “escape cultivation?”
