This lily is over 5" when it is mature.
It has the same kind of bone type bulbs as the Lankongense.
The same kind of leaf arrangement on the stem as a martagon.
It blooms in July

Well, I haven't had lots of experience with species lilies, but I'll suggest L. pardalinum?
:)
Am I far off the right track???

Thanks, Calin! I thought of that too . What made me wonder is that it is suppose to like moist soil and I am on sand and I don't always get everything watered. It doesn't have the yellow markings like the pictures I've seen of the pardalinum and I live in zone 3, yet it is thriving here. Perhaps there is a variety of Pardalinum that tolerates those conditions, I'm hoping someone will know.

Is it something you bought or something you found growing in the wild? If it is a wild plant, you might compare it to Lilium michiganense: http://en.wikipedia.org/wiki/L...

If it is a cultivated plant, I have no guesses.

Looks a bit like Martagon Tsingense

Thanks Guys, I ordered both yellow and the red/orange Canadense from B&D Lilies a number of years ago this is one of the lilies I got. I notified them that I hadn't gotten the right lilies and they refunded my Money but I had no idea what I did have. The flowers on both lilies are basically the same. The flowers on both looked like the one in my picture but the one in the picture gets a lot taller and the stem is much heavier than the other. They also sold Superbum at the time and it looks a lot like that but because of the zones and moisture requirements of both Superbum and Michiganense I've been hesitant to identify it as that. You think it's possible either of them could thrive that far out of their zone?

Lilium michiganense is native in Minnesota up to the Canadian border so I don't think hardiness is an issue. Prairie Moon Nursury has pictures of the bulbs if that helps at all: http://www.prairiemoon.com/pro...

Kent that must be it! Thanks I'll mark it done.

L. pardalinum has a different kind of spots and recurving of petal. You definitely do not have that. L. canadense petals do not recurve so strongly, needs more moisture than the others mentioned so far. It's not that one.

L. superbum is more common commercially than L. michiganense, but both are available. Even botanist have difficulty tell these two apart. Natural distribution of the two hardly coincide, L. superbum being eastery, L. michiganense being (mid)westerly. It certainly looks like one of them. If the flower center (at the base of the petals) is green, it is likely L. superbum. If not green, it is likely L. michiganense. My best guess is L. michiganense. All four of the species I've mentioned have the bone-like bulb structure, but L. lankongense does not.

Rick, Thanks for your response. I'll have to look at the center next summer to see what color it is. I have another one that the flower looks very much like the one in the picture that I was allowed to dig out of the ditch because they were redoing the road. It's shorter and the stems are not nearly as heavy. I'm thinking because it was growing wild here that it is probably the L. michiganense. I appreciate your knowledge and your help.

L. superbum does not occur in Minnesota naturally.

Any Lilium sp. growing natively in Minnesota with that kind of bulb structure must be L. michiganense.
