Wanted to show off my Erythrina crista-galli-I live in Zone 8a. At first, it died back to the ground every year and now the trunk is large enough that only the small branches die back. It made it through snow 2 times last year. Even when it died to the ground every year, I treasured it. It brings me joy every time it blooms. Now, when it blooms, it is spectacular and the flower spikes extend over 4 feet long and it is covered with blooms. It appears, I have created a micro climate in my yard.
