Orchidaceae
Botanical Name
Ludisia
Plant Common Name
Jewel Orchid
General Description
Admired for beautiful jewel-tone foliage as well as small spires of delicate flowers, the tropical terrestrial species in Ludisia are beautiful as both houseplants and outdoor specimens in frost-free climates. At one point botanists recognized as many as six separate species but now only Ludisia discolor (synonym Haemaria discolor) is considered the lone species in the genus, though some also accept Ludisia argyroneura (synonym Dossinia marmorata). In the wild it inhabits the moist forest floors of Malaysia, the Philippines, Indonesia and Burma.
The linear leaves are purplish with parallel leaf veins striped with cream and dark green. These are evergreen and look great all season long if weather remains favorable. Spikes of small, white flowers are produced in winter. These are insect pollinated and pods filled with microscopic seeds follow.
One odd fact is that most orchid flowers twist upside down as they age. When they first open their floral lips, or pollinator landing pads, are on the upperside of the flower and as they are the lip rotates to the lowerside of the flower. The lip may twist clockwise or counterclockwise. Most rotate by 180° but a few twist to 360°. It is believed that this facilitates the timing of pollination and serves as a cue to prospective pollinators.
Grow jewel orchid in fertile organic-rich loam or potting mix. It grows best in bright but filtered light and requires warmth and high humidity. Orchids are thought to be difficult to grow, but Ludisia is quite easy. Place on a tray of rocks, to increase drainage and humidity and water and feed regularly.
