Showy, fleshy, fragrant flowers are produced on axillary, arching to subpendent racemes or panicles.

A prominent feature of this species is the midlobe of the labellum, which is oblong, obtuse-subacute, and the apex is covered in dense trichomes.

The colouration is however a very transitory trait and various intermediate forms between red and white occur.

The floral phenotype even shows temporal variations within singular individuals in subsequent seasons.

The taxonomic changes have only been sparingly adapted in horticulture and plants are often still sold as Phalaenopsis speciosa.
