I have know idea if the "tiger" lily that I have is a species or cultivar. It did not set any seed but a profusion of bulbils. The stalks are dry and the bulbils are forming roots. I just harvested them and, since I have not done this since I lived in the Pacific Northwest of the United States I am wondering if I should just plant them or should prepare them so that they can develop their roots in cool shade and then chill them later, which occurred naturally where I lived before. Any suggestions appreciated. Randy Monterey Bay Area, California
