Cyrtanthus falcatus—green flowers

Bob, Steve, and Arnold,

I’m willing to believe that temperature has an effect on color intensity—I’ve seen it in my orchids and vireyas—but C. falcatus must be exquisitely sensitive if too much warmth is the sole cause of these green flowers.  I had the plant on the floor of the greenhouse, near the poorly sealed door, so the temperature was probably 10-20 degrees lower than the 58 F thermostat set-point on cold nights.

I have found C. obliquus much easier to flower, so I suspect that C. falcatus wants something I haven’t given it.  Maybe average temps are too high, even though winter nights are cool.
