Cereus Night Blooming Cactus

My smaller Cereus cactus bloomed the other night. I was hoping to put a webcam attached to a Raspberry Pi computer to time lapse photograph it opening and closing during the night. The night the bloom opened I only got the camera set up late in the morning so the bloom pod had already mostly closed.

I did capture a small about of video of it for several hours which I need to figure out how to edit and put on YouTube.

Interesting enough it looks like amazon.com sells seeds for a blue variety of this cactus.

The Cereus Night Blooming Cactus

The Cereus peruvianus cactus bloomed on August 17, 2012. These pictures were taken about 11 PM EST and the flower probably fully opened up around 2 AM. It then closes by the time the sun is up. I assume the plant does this to conserve water being a desert plant.
