Check the wiki, Dennis. There you will see some photos of Lilium grayi growing in my garden. Seed of Lilium grayi and seed of Lilium pardalinum germinate under very different conditions. They both germinate hypogeally, but Lilium grayi seed requires roughly three months of moist WARM conditions to form a tiny bulb. Then, after about three months of cold conditions, it produces the first leaves. Note that the name is properly grayi, not grayii. Lilium grayi may well be a relict species: it seems to grow much more vigorously far to the north of its current natural range. Jim McKenney Montgomery County, Maryland, USA, USDA zone 7, where Lilium grayi has grown well for years.
