|Phalaenopsis stuartiana bears branching racemes, to 3 feet long, of white flowers with yellow markings and brownish red spots on the lower sepals and lips, to 3 inches wide. Borne in winter.
This epiphyte is named for its blossom that resembles a moth. Better suited to advanced gardeners than the beginner, this orchid requires warmer, more stable growing conditions than most. Leaves are borne from short, thick, upward-growing rhizomes and are elliptical and dark green and sometimes speckled or mottled depending on species. Flowers are long lasting, forming at the base of the leaves, and simple or branched racemes.
Orchids are sporadic bloomers and, if happy, could flower up to 3 times each year. Give this orchid plenty of light and a steady humid environment, occasionally misting leaves. Provide ample water from spring through fall and fertilize monthly with a balanced fertilizer. Orchids are traditionally grown in a loose, bark mix. Cut back spent racemes when flowering is complete.
