Hey, late comer to the thread.
I have two of these - a male and a female (just worked out that way. Lucky me).
The female is a great, big grower, and happy in just about all conditions.
The male is a little pickier, and more compact, but still going.
Both suffered from lack of light this winter (along with everything else in my greenhouse) to the point that I put light fixtures on my b-day list so I rig some supplamental lighting for this coming winter (watch it be sunny the whole season....just watch).
I've actually just fertilized the female spikes with pollen from my "sold as" macfarlenei, but it's much more likely a hybrid, as it doesn't look like any macfarlenei I ever saw. Still cool looking, with a complete maroon flush, so I hope to get something cool....
I just noticed my earlier post - it seems my female may not be from SR....but then where did I get it? The plot thickens as my memory wanes.
