Rose-pink flowers are produced on erect racemes. This species has been found to be tetraploid with a chromosome count of 76 chromosomes (2n = 2x = 76).[3] It similar in appearance to Phalaenopsis pulcherrima, but it has larger flowers, larger leaves and longer inflorescences. These attractive features creates a high demand of the species.[4] Problems with fruit set may arise in the creation of interspecific hybrids.[5]
