Below are two examples of Trudy Slocum night blooming tropical water lily. The blossoms are fully 8 inches across, the biggest I've ever seen, and look stunning. They open after dark, and remain open until 10:00 or 11:00 the following morning.
Below is a Red Bog Lily. I've had it several years, but this year (2010) was the first time it's bloomed for me.
