This doesn't look very appealing, but I suspect the photography, not the flower, is at fault, since there are all sorts of neat pictures of this plant in Google Image Search.
Also, once again, the label at the show was misspelled -- it's Dendrobium Pixie Princess; not, as the tag had it, Pixy Princess.
It's like they're not even trying.
But the flowers are nice regardless. Look 'em up in Google yourself, if you don't believe me.
