This is Paphiopedilum Sorsorcer's Stone (Stone Lovely X Pacific Shamrock).
Last year, it bloomed in December, but this year, it was already in spike in the middle of summer and the flower opened up about a month ago.
It is quite large with a natural spread of 15 cm.
There is a second spike developing. I hope I get to see both in bloom together but not sure.
This plant is a good grower because it added four new fans in the past one year! Yes, I got it as a single growth plant.
Now I have a bunch of others in bud or low spike.
Yay!!!
