Rare in my area, I found this plant growing wild in two different places in 2007. Both were growing on barbed wire fences just above creek bottoms. See my pics. The flowers aren't exactly scarlet, but seem to be the same plant. If I've put it in the wrong category, I'll be happy to make corrections.

Also a wonderful choice for southern gardens, she doesn't mind the heat and pretty bug resistant.

We've had good success with Princess Diana. Comes up somewhat late, apparently requiring more warmth than many other cultivars, but grows and blooms vigorously and the flowers are long-lived. Winter is not a problem in zone 6.
