For 2026, Plant Delights/JLBG are pleased to share Aconitum superbum 'Kupres', an amazing monkshood that Hans Hansen and I spotted at 4,200' elevation near the town of Kupres, Bosn ia in 2012. I didn't think this high elevation form had a chance in our hot summers, but after seeing Hans' success in Michigan, we gave it a try. Shockingly, it also thrives in Eastern NC, growing in full sun with consecutive weeks at 90-100 degrees F. For us, starting in late September, the 4' tall stalks are topped with clusters of large blue-violet flowers. Show more
