True blue...
 

Blue is an unusual color in the plant world in general, and certainly among orchids. "Coerulea" is blue-violet, not truly "blue". Cleisocentron merrillianum is definitely blue - tips of the petals are almost turquoise. The patch of deep purple in the throat is a nice contrast. Its close relative, Cleisocentron gokusingii, has flowers that look identical. Clctn. merrilianum has long terete leaves, Clctn. gokusingii has shorter, semi-terete leaves. Both can bloom several times a year. The blue color is more intense in cooler weather (which what it's getting IS NOT) but this still is quite a nice blooming.

Color is accurate - photographed in daylight, no post-processing. Plant is growing on a slab of wood shingle with sphagnum under it, the basket was just to hold the mount in place for the photo.

Wow! Thanks for sharing these photos.

Beauty!

I like the shape of the blooms. And the color is excellent also. Being color blind, I don't see blue very well in anything. But I will take your word for it that this is a true blue color, Roberta. :-)
