Benary's Giant Deep Red zinnia (Zinnia elegans ‘Benary’s Giant Deep Red’) features fully double, deep red 4- to 6-inch blooms on thick, sturdy stems. This plant thrives in the heat and humidity of Chicago summers (nice to know at least one species is enjoying Chicago's often humid summer). This cultivar is highly disease resistant and attracts bees and butterflies. It's a great, quick growing choice to fill in holes where less heat-tolerant plants have ‘melted’ out.
