Vernonia 'Southern Cross'

This perennial is known for its strong constitution and rigid stems, thriving in low-maintenance settings like rain gardens and perennial borders. It is ecologically beneficial, attracting late-season pollinators and providing seeds for birds. Compact cultivars like this one are excellent additions to cottage gardens, offering reliable late-summer color.
