Dendrobium unicum
Native to Thailand, Burma, and Laos, this is a wonderful miniature that can grow to specimen size with hundreds of flowers in bright orange. The lip is a light orange/yellow with red veins. The fragrance is exactly like freshly sharpened crayons.
The plant is kept at the eastside facing windowsill. I grow it in brighter light in the winter months, and keep shadier once new growth develops.
Intermediate. 60-63 degrees Fahrenheit at night during Fall and Winter. Although I know this is an equatorial plant but in the monsoon rains it can get cooler in those areas of origin. This plant loves summer temperature ranges, as long as it is shady.
Humidity at least 50% or higher in my room with a portable humidifier; but humidity trays can also be useful.
I water as the mix approaches dryness but I do not allow the mix to become completely dry between watering. Overwatering can cause several problems such as root rot and infectious bacteria/fungus in the potting medium.
The flowering season is usually in the early spring months from February to April. Brighter light during this period will help to encourage more flowers. When the flower buds emerge, the leaves on the canes typically begin to fall off. This is a first bloom from this 2 year old seedling.
