Vernonia x ‘Summer’s Surrender’ – Ironweed – 1.25-Quart

Developed by Jim Ault at the Chicago Botanic Garden by crossing Narrowleaf Ironweed (V. lettermannii) from the Ozark Mountains and Tall Ironweed (V. arkansana) from the midwest and Ozarks. It inherited the bushy habit of V. lettermannii and the more robust plant size, larger foliage, and larger capitula of V. arkansana. ‘Summer’s Surrender’ is no shrinking-violet perennial, as it matures into a robust yet uniform and dense broad mound, larger than the other CBG introduction, ‘Summer’s Swan Song’ and a little less tolerant of dry soils.
