My North Creek Nurseries Wish List

The most diminutive of hybrid ironweeds available on the market, ‘Summer’s Swan Song’ is a selection from our friend Jim Ault at Chicago Botanic Garden. The foliage is olive green with a purple tinge on wine red stems and covered in deep purple flowers from early to mid-autumn. Attention-grabbing at CBG’s Vernonia trials, the long flowering branches interlock to hold the stems upright on the blusteriest of days.
