To my friend Craig, if you sat they're tiger lilies, and I know what you're talking about, I guess they are tiger lilies. The one shown here is the double form, which is not at all unusual. Daylilies are mostly sterile, and are spread by whatever critter or machine moves the tubers. The buds are eaten in their native Asia, but I don't recommend it. I once met someone who was sickened by eating them. Apparently they can pick up toxins from the soil they are in. Imagine that! Toxins along our roads.
