P. moranensis...

For heaven's sake, this silly flower has been sitting there, about 10 % open for at least two weeks....What gives? Will the darn thing open all the way or what?

I have noted at home that the opening of the flower depends on the humidity percentage and temperatures for my Mexican or other tropical species.

For exemple, a Pinguicula filifolia flower or a P. sharpii only really open if the humidity is about 60% more, the flowers are more closed. For P. filifolia, the pollinisation seeems to work only if the flowers are opened.

At home, with average temperatures of 25°C, the flowers open in 2 days when the scapes have reached his good lenght.
