Dear Orchid Friends:

Ludisia is the genus and the species is Ludisia discolor (aka Haemaria discolor). The species is native to Indonesia and Burma. There is a variety known as Ludisian discolor var. dawsoniana. Ludisias are terrestrial orchids which means they grow in soil and soil-like medium and grow on the ground. This is one reason why they are easily mistaken for houseplants! Ludisia can be grown in the yard as ground cover as a low spreading plant. Plant them in shady, moist areas with excellent drainage. Potted, Ludisia spreads to overtake the pot and matures into a large specimen plant. These orchids are characterized as relatively difficult to grow.

Temperatures: Ludisia tolerate intermediate to warm environments. They need high humidity and warm temperatures. Because of these temperature preferences, they can be grown in terrariums either directly in the terrarium medium or placed in pots.

Light: Low to medium light is ideal and they do tolerate extremely low light levels. Protect them from bright light and strong sunshine. In the yard, plant them in moist, shady areas.

Watering/Potting Medium: Ludisia are terrestrials so grow them in a mixture of soil and peat moss. You may want to add a little perlite to your mixture. Keep the medium mosit but ensure good ventilation in the area they are growing, Good drainage is also essential. Keep evenly moist. If plants are indoors, more frequent misitng and watering may be necessary if using the air conditioner or heat. Remember, they like humidity.

Flowers: Flowers are white with twisting yellow columns. Individual flowers are small but grow in clusters on upright stalks. Flowers usually form fall to winter during cooler weather. The large specimen plants produce a showy display of inflorescences.

Frequently, one hears comments about the unattractiveness of orchid plants when not in bloom. Ludisia is uniquely different and is a perfect plant to simply enjoy their beautiful foliage. They make great houseplants (when mastered). If you have a green thumb, you may want to try your luck with one of these plants.

Until next time,

Vivi

P.S. Summer is here and insects are active during these times. Check your plants for spider mites, scales. Observe your plants leaves and undersides. Remove old dried sheathing to prevent scales from having a hiding place.
