Frequently distributed as the much rarer U. minutissima, this tropical Asian species develops mats of tiny grass-like leaves across the surface of the soil, and thin stalks bearing one to several exceedingly small but intricately colored flowers that sport short spurs and two broad lower lobes in shades of purple, yellow, and white. An easy terrestrial species, though may flower best in seasonal environments or changes in moisture levels.
Plants are sold as 0.5-1" wide/deep plugs.
