Vernonia noveboracensis (new york ironweed) has large umbel clusters of purple flowers and forms a very tall, large clump. It may require staking in windy areas. It makes an impressive statement in the back of the garden. We have cut it back by one third around June to reduce its height and it still flowers magnificently. It stands tall all winter with the finished seed heads forming stars. Native Ontario perennial.
