Allium jesdianum ssp. angustitepalum was previously sold as A. rosenbachianum (a very different species). It seems that the nomenclature is sorted out. I like this species as it has beautiful two-toned flowers (rose-purple and prominent white stamens), held in graceful hemispheres, on stems only about 24-30" (60-75 cm). There are several named cultivars, but I like this subspecies the best. Photo by Mark McDonough.
