Wildflowers: Is This a Wildflower?

Found this flower on a densly wooded (oak, madrone and manzanita) hillside in Southern Oregon. The plant and flowers resemble a daffodil. This is in a reasonaby isolated area and so it's not likely an escapee from someone's garden. I note that all three flowers branch off of a single stem. I searched the entire area and failed to find another one. Anyone want to venture a guess?

 

Definitely a 'tame' flower - a double-flowered daffodil cultivar. Double flowers like this don't occur in wild plants. So it is an escape, however remote the location!

 

Thanks Michael,

I had my doubts that it was a wildflower, but there it was in the middle of a manzanita patch in the middle of nowhere. Of course I will now be tantalized with the question of how in the world it got there.

 

Birds or anything else that may have "picked up" a seed and "dropped" it somewhere else. haha

 

Since it's a double likely to have been planted there. I've seen single clumps of other kinds of exotic (non-native) plants along trails way up in the mountains. As with this narcissus, quite likely to have been put there by someone for their own amusement.
