I love black-eyed susans and this is one of my favorites. It is doing very well here. Winter here was extremely rainy and I thought they were going to rot but they didn't. They color is beautiful.

A big puffy flower. Some had more layers of petals with a closed eye that I preferred better, and some had less layers and open black eyes. Fair amount of leaves per flower if you are counting.

This is my first year growing this variety, so far I like the blooms and the plant is growing well. Will update this note if it does not perform well when the summer heat and humidity set in.
