I found this plant in 2009 near the village of Gualea in Pichincha Province of Ecuador. The location where this plant was found is at 1500 meters in the pre-montaigne forest of the Andes western flank in northern Ecuador near Sitio Tulipe and the cultivar name derives from that locale. This area is known for its high number of endemics. More on the location at - about the Yumbo people who were the ancient inhabitants of the region.

The plant was very tall and had a rounded inflorescence with yellow, open labellum flowers similar to Costus glaucus. The stems were dark purple in color unlike the normal glaucus new stems of the species by that name. The plant flowered in cultivation in 2015 and is now determined to be closer to the new species proposed by Paul Maas, to be named Costus antioquiensis. It has the same sheathing of the inflorescence as other examples of this species that are found in the mountains of Colombia - including the cultivars 'Lemon Chiffon' and 'Nirvana'. A thumbnail page showing photos of this plant can be found at

DNA has been extracted from a tissue sample I sent to Cornell, and perhaps when it is included in the full molecular phylogeny, that will shed more light on its proper classification and relationship to the other species.

This has been given a tentative name as Costus 'Tulipe', but the cultivar name has not yet been registered and the plants have not been released to the public for cultivation.
