Oxalis versicolor - aha!

I have been waiting weeks for my pot of Oxalis versicolor to open its 
buds.  On the infrequent days that the sun shines into my attached 
greenhouse, I make sure the pot is being shone upon.  All to no 
avail.  Not a single flower has opened.

Today is one of our common gray days - the weather report gave a 
promise of sunny breaks, but the fog hasn't burned off yet.  I 
decided to try something different, so I brought the pot into the 
warm living room.  Guess what?  Yes, half of the flowers are open. 
So it is heat they want, not sun.

The greenhouse maintains itself during winter between 5 and 10 
degrees celsius.  (about 40 to 50 degrees Fahrenheit).  My living 
room is heated to 18C (about 65F).  I should walk my pot of oxalis 
around the cooler parts of the house to see what its precise 
requirement is for opening.
