Dendrobium unicum Seidenf. is a unique Thai orchid because, after the 1st year, it sheds its leaves before flowering. This is the reason that Dendrobium unicum got its name.
The Thai orchid,Dendrobium unicum, is known in Thailand as “Euang Krang Saet” (เอี้องครั่งแสด). Dendrobium unicum is classed as a miniature orchid and is an Epiphyte, which means that it attaches itself to and grows on other living plants but also can be grown successfully in a small pot.
The flowering period of Dendrobium unicum is February – May. Native to Thailand, Myanmar, Laos and Vietnam, Dendrobium Unicum can be found in Thailand in the evergreen and deciduous forests of the North and Northeast of the country. The flowers of Dendrobium unicum have waxy orange red petals and sepals with a pale orange lip marked with dark orange veins and also have a middle keel. Flowers are about 3cm across. The flowers are fragrant and have a scent similar to children’s wax crayons. The flowers are best viewed in an upside down position as shown in the photos below taken in our Chiang Mai garden.
