When I snapped this photo of my first ever bloom on this Lady Slipper Orchid on May 9, I was a little concerned as it did not seem to match the description: "cream colored pouches with some pink and cream streaked petals and tendrils". I have two different Cypripedium plants and I thought I got the labels mixed up.
Look at the change in appearance in this photo of Cypripedium 'Aki Pastel' taken on May 18. Yes, this is the same plant and no, I did not mess with the photo. Over the course of nine days this flower clearly matured into the plant described above. In the time since this second photo was taken, it has not changed any more, but I consider that a fairly dramatic transformation. The other orchid did not bloom this year so I will have to wait to see if follows a similar pattern.
