A couple of big ones are blooming in my neighborhood right now, too Gordon. The one in the yard across the street from me has had no care for over 10 years as the house is abandoned. No water, no fertilizer, nothing. It's growing under a big live oak tree, and is quite close to the trunk of the tree, too. I've always wondered how it survives, let alone grows and blooms.
They bloom at this time each year, when we have cool, damp weather going on. Foggy some mornings, cloudy and high humidity. Have you tried misting them with cool water? Might help the leaves to stay open/alive.
I'll get some pictures tomorrow.
