Vernonia Summer's End

‘Summer’s End’ begins to show interest during the summer months as it grows into its uniform, upright habit while displaying its thin, wispy foliage. It is most attractive in bloom during late summer to early fall when few other perennials are in bloom. 'Summer’s End’ is intermediate in size compared to the two previous releases and is similarly a highly upright cultivar with no stem lodging. Inflorescences are abundant and form a mass of flowers that consistently attract pollinators. ‘Summer’s End’ is drought tolerant and disease resistant and should provide a vibrant, lively presence to any garden late in the growing season under sunny conditions and in well-drained soils. While most ironweed taxa are found in mesic habitats, V. lettermanii, one of the parents of ‘Summer’s End’, can be found in drier rocky uplands. ‘Summer’s End’ appears to have inherited tolerance to both high soil moisture and drought, though plants perform best in well-drained soil with uniform moisture availability. Mulch can be used to preserve moisture in drier soils. Plants also do best in full sun with good air circulation and should not require staking. Winter stems remain upright and rarely break off. Old stems can be pruned away in late spring.
