My last three Den nobles are just beginning to bloom. There is Wave King 'Akebono' which is similar to Comet king but with a larger flower and more purple. Fancy Angel 'Lycee' with very soft colors and Yellow Pansy 'March' whose flower is much more slender than the others. I have noticed that the colors darken with age so it will be interesting to see how Yellow Pansy changes color.
These three are the most alike. The biggest difference is the amount of purple and white. Lucky Angel 'Smash' is on the left with Comet King in the middle and Wave King on the right.
I love my Yamamoto Dendrobium. It's my first one and still has a few blooms on it though I purchased it in bloom a few months ago. It is Line Dance 'Minuet' and has a very soft and pleasant fragrance. Congrats on all your lovely blooms!
