We have yellow flag iris (not to be confused with Louisiana iris or blue flag iris). That said, there are better alternatives for emergent flowers and bank stabilization. The biggest downside to them is there invasiveness. Cattails have the same issue. I use giant burreed as an alternative to cattails. Suggest yellow water lilies to add some yellow flowers to the mix.
