What is Cypripedium Insigne?

Scientifically known as Paphiopedilum insigne (Wall. ex Lindl.) Pfitzer, Cypripedium insigne is an orchid. It's not just easy to grow, but also grows fast. The terrestrial plant is categorized under the Orchidaceae family and the Cypripedioideae sub-family.

Commonly known as the twin-flowered lady's slipper, the terrestrial orchid has many synonym names. It is also referred to as Cypripedium chantinii, maulei, moensii, maximum, forstermanii, amoenum, sanderianum, tresederi, nilsonii, sanderae, wallacei, speciosum, cypheri, biflorum and amesianum, just mention a few.

The many synonyms used to refer to this orchid is a clear indication of the difficult, misleading and complex process orchid experts undergo trying to classify it taxonomically. The rare plant is native to China and northeast India. The orchid populations in Thailand and Bangladesh have significantly reduced over the years.

Ruthless international and regional trade, plant habitat degradation due to animal trampling, human disturbance and deforestation, and exploitation of Cypripedium insigne for its horticultural benefits have been attributed to its reduced plant population in Bangladesh and Thailand.

The plant has been declared an endangered species with possible extinction in Thailand, Myanmar and Bangladesh. It is listed in the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) under Appendix I, Annex B.
