I found some beautiful irises for sale locally and decided to plant them about a month ago. We've had a lot of rain so they're doing okay in the sunny spot I placed them. Some of the leaves are half brown, half green. I did a little cleaning up this morning to remove the dead leaves and even done healthy looking leaves pulled up... Like they were too wet. Just looking for advice on irises... What is the likelihood they will make it through the scorching August heat in Georgia? If they dieback will they return in the spring?
