Promenaea xanthina 'Botanica'

Promenaea xanthina is a miniature orchid from Brazil that produces an abundance of lovely yellow flowers when well grown.  It belongs to a genus of about fourteen species, all from Brazil.  The plant have angled pseudobulbs and soft greyish-green leaves, two per pseudobulb.  The flowers are produced from the base of the pseudobulbs and the plants generally prefer cool temperatures.

My plant of this species is 8-10 cm tall and the flowers are 5 cm in size, a bright clear yellow with some spotting at the base of the lip and column.  They open widely and have a very typical "orchid" shape.  My plant blooms in early summer and is grown in a plastic net pot and live sphagnum and seem to bloom best when the plant is undisturbed and beginning to overflow its pot.
