(aka: A. peninsulae) Arisaema 'Ulleung Treasure' is a remarkable 2009 Plant Delights/JLBG introduction.All I could do was stare when I first saw this gem in the extinct crater that is Korea's Ulleung (aka Uulong) Island. We had seen lots of silver-centered arisaema during our hike, but none like this. The 3' tall stalk was jet black, the wide 12-leaflet leaves were mostly silver with a band of green around the edge, and the dramatic black-striped flower was held just above the foliage...true perfection! In the garden, this has drawn raves from garden visitors and, thanks to the magic of tissue culture, we can now share this special clone with gardeners around the world. It has proven easy to grow in rich garden soil, albeit slow to offset. See if you agree that it's the best arisaema you've ever grown. Young plants may take a season to express all the mature characteristics.
