Warm to cool grower from Indian, Burma, Thai and Malaysia. It's officially a warm grower but some one told me to grow it cool. I split the plant and have one warm, the other cool. The coll growing one is in bloom. The other one is also growing but no flowers yet. Probably does not mean anything. The regular one has the same mottled reddish color throwout. See Jay Phal's site where he has a picture of the regular and the dark varieties.
