I have not had much success with Irises here in Mobile. I believe the soil is too acid. But, it doesn't stop me from trying. I have them planted all over this place. There are bearded ones, native iris, water iris and african iris and probably some others growing here.
My friend owns one of our area's "Treasured Forest" and I shared some of the water irises for his pond. They naturalized and are beautiful.
I spent today applying bonemeal to the irises and other bulb plants.
