Vernonia x ‘Southern Cross’

Do you have room in your garden for a late summer/early fall blooming perennial that attracts butterflies galore? This Ironweed has dreamy clouds of composite purple flower clusters on sturdy stems 3-4’ tall beginning in August and its handsome narrow foliage looks fresh all season long. Discovered by Brent Horvath of Intrinsic Perennials, ‘Southern Cross’ obviously has the species lettermannii in its heritage. This selection combines beautifully with ornamental grasses such as Sorghastrum, Schizachyrium and Eragrostis.

‘Southern Cross’ appears to like extra moisture the first season but becomes more drought tolerant once it is established. Plants are hardy in zones 4-8 and should be deer resistant.

  1. I don’t know Vernonia ‘Richard Simon’…will have to look for it. We have one called Vernonia angustifolia ‘Plum Peachy’ that we purchased from Plant Delights a few years ago, but it hasn’t increased in size very much for us. Still trying to decide if it merits attention.

  2. In Massachusetts I had a late blooming mum, possibly called Clara Curtis. It was pale pink and very hardy and I would like to add it to my garden in southeastern Pennsylvania. Where to buy it?
