Paphiopedilum concolor is one of the warm-growing Paphs in the brachypetalum section and it shares the beautiful mottled leaves of its cousins. It is found in Burma, Thailand, Laos, Vietnam and neighboring areas at elevations up to 1000m. Typically, it grows in detritus on limestone rocks under shady conditions. It was described by James Bateman in 1865. Paph. concolor has been used as a parent some 100 times to produce compact, temperature-tolerant hybrids. The variety ‘hennisianum’ refers to a richer yellow color than typical.
