Description

Vernonia x lettermanii 'Southern Cross' is a relatively short, vase-shaped, hybrid variety growing only 3'-4' tall, with simple, narrow leaves on stiff, upright stems. It is topped in fall by showy, flat-topped clusters of bright purple, fringe-like flowers that create an airy dome of color.

Vernonia is a widespread North American native perennial that is found in most of the United States east of the Rockies. V. lettermanii is found in Oklahoma and Arkansas. The other parent(s) of this cross is unknown. With its fine foliage and upright stems, 'Southern Cross' resembles Amsonia hubrichtii when not in bloom.

Vernonia 'Southern Cross' prefers full sun and average, well-drained, fertile to poor soil. It is drought tolerant once established.

We ship via UPS & USPS (the Post Office), and their ship rates are automatically generated through our site. We do not profit on shipping costs. We are working with these providers to get our customers the best rates possible.

All ship times are subject to change if extreme weather conditions are present here at the nursery or at the shipping destination.

Please note: Depending on the time of year, the foliage of the plants may be trimmed to fit into our shipping boxes. This could delay the flowering of the plant, but many perennials actually benefit from being cut back.

We are currently not able to ship to Puerto Rico, Hawaii, and outside of the US.
