Here is another breakthrough in lily breeding, tender orientals crossed with hardy asiatics! As I planted these in the Fall of 2006 for the first time, I am now able to give a true evaluation of their hardiness and performance in the garden. At present, I can tell you they overwinter without extra protection and although they come up late in spring, each one comes up and blooms profusely, even those of small bulb size.
If you are in Zones 1 to 2, and if you have not planted these previously I suggest mulching them for winter, planting deeply and only in spring to help ensure they overwinter in your garden the first year. They are hardy for all other zones. Another alternative, if they are not hardy in your zone is to overwinter them in pots.
