This is interesting, since I noticed this last winter distinct differences with different species as to their ability to open their flowers when the sun was not shining. Within the 'tribe' O. obtusa, there are several large-flowered ones that seem to need less sun. In our catalogue these are: O. obtusa tangerine, amber and coral. We have others that aren't listed. They open their flowers in the early morning before the sun has reached its full intensity, and stay open longer too, and also open on dull days. My business associate and I wondered last winter if this is a distinct group different from the others. The flower structure and bulb seems very similar to the other obtusa species, although the petals do not overlap in these species and they are much larger than most others in the group. We think they are a different species, but without much to go on in the literature we still lump them all together. I have to say that the species we list as O. comosa falls in this category also. It came to me from Michael Vassar labeled as O. comosa, and I have left it with that moniker since I don't know what else to call it, but, honestly, I don't think it is correct. It opens on dull days and also stays open late in the day. O. fragrans is the one that opens in the evening and stays open late. I brought a pot into the house, but the scent was so overwhelming I had to put it outside on the porch. O. livida grows and looks much better in some shade, so I think that would qualify also. Maybe next winter I will try to note which species are open on dull days so that I don't have to rely on my inadequate memory. The early blooming species are O. commutata and O. lobtata (highly recommended) - both are also strongly scented and bloom as early as August to September. Late blooming ones are O. incarnata (can be a pest in the ground), O. inaequalis and O. bowiei. There are probably others that I am not remembering.
