On the Ludwigshafen Park-Insel there are old mixed populations of the ornamental Hybrid Glory of the Snow Scilla luciliae x siehei and the wild Alpine Squill Scilla bifolia s.str.. The hybrid and its parents had formerly been separated in genus Chionodoxa. Also hybrids between the two taxa can be found there. They can be recognized by the faded bright center of the flower and expecially by the intermediate color and position of the stamens, because the stamens of the former Chionodoxa are yellowish and are standing vertically, while the dark stamens of Scilla bifolia are arranged horizontally.
