Well, that’s just the very best hosta ever developed, Hosta plantaginea. You have good taste indeed. There are some cultivars involving its genetics, including ‘Honeybells’ and ‘Aphrodite,’ I believe, or the straight species. Read more about fragrant hostas and the influence of H. plantaginea here, on hosta king Tony Avent’s site. http://www.plantdelights.com/Tony/fraghosta.html Obviously he is selling some of the good ones of these at his nursery, Plant Delights (in my sources or above).
