Hi Stacey
That's definitely two Dendrobiums in one pot
Last month, a club member brought in an arrangement that had 4 different Dens in bloom...it was awesome!
Most Dens like high light.
Here's some info for your Den Burana Fancy:
Den. Burana Fancy is composed of species of which 34% take high light. It may be tolerant of bright indirect light conditions.
Den. Burana Fancy is composed of species of which 40% take hot temperatures and 34% take intermediate temperatures. It may be tolerant of intermediate (68°F to 75°F or 20°C to 24°C) and hot (75°F to 85°F or 24°C to 29°C) night temperatures.
50%-60% humidity. Keep moist in the Spring-Summer, when plant is in active growth. Grow in a pot with porous, free-draining media. The pot should be small for plant size. Fertilize weekly, weakly (one quarter to half the normal dose). Reduce water/feeding during the cooler months. Common media: fir bark, coconut chunks.
Den Salaya Pink is not a registered hybrid...I have the same plant and have never been able to find any info on it. I grow it in basically the same conditions listed above.
Very pretty arrangement you've got there
