📖 About this plant
Known as ‘dancing lady orchids’ for their charming flowers that resemble tiny, winged dancers in yellow dresses. The typically yellow flowers with brown or maroon barring are borne on long, branching sprays that can carry dozens of blooms. Modern intergeneric hybrids (such as Odontocidium, Wilsonara, and Colmanara) expand the color range to include red, pink, white, and green. Prolific bloomers that can flower twice a year under good conditions.
