Vernonia lettermanii 'Iron Butterfly'
Vernonia are well-branched with prolific late season blooming to add vibrant color to the border. Iron Butterfly comes from Dr. Allan Armitage's trials at the University of Georgia. Drought tolerant, full sun plant is a butterfly magnet.
Prefers humus-rich soil with good drainage but will tolerate a variety of soils, even dry and rocky ones. Can tolerate brief periods of flooding. Can be divided and transplanted late fall or early spring. Can be cut back by 1/2 in midsummer to control height. Will self sow.
Our plants are grown in 3.5x3.5x4” plantable pots. Made from 100% biodegradable coconut husk fibers (coir), these pots have tremendous advantages over plastic pots. With better air exchange, this "breathable" pot fosters robust root growth and reduces transplant shock since you can plant the pots directly in the ground. The pot naturally becomes part of the soil on its own over time—no composting required—and since they're made from a renewable resource that requires very little energy, they're earth-friendly too!

Please don't hesitate to contact us if you have questions or concerns—we share your passion for gardening and want your new plants to thrive in your border!
