Beautiful image, Ken. The composition is really superb - Nice, tight image with good clarity and detail. I think if you had taken one more step to the left you might have included a bit more of the green buds and that little piece of the petal on the left side that is missing - it might have made the comp even stronger.
Still...I love it. Great colors and really nicely executed.
Looks like a tiger lily to me...they grow wild in my part of the woods.
