Rather than constant high temps and humidity, I think this species may want bright light but lower water in winter, at least that is what I give mine. Humidity in summer in my cool house averages between 55-70%, a little higher inn winter. I left them on the benches outside all year for a couple of years and, although I got good growth, no bloom. Once they went back into the cool house, no problem with bloom.
White Rabbit, there are some lovely variegated leaf forms, any one of which you could easily turn into an ornamental foliage plant. Keep your eyes out for them!
