This is a tropical plant, Night Blooming Cereus. It blooms once a year, usually in the summer, and only at midnight. It takes about 4-5 days from small bud until it’s fully opened around midnight. Its bloom is spectacular – anywhere from 10-12 inches across and its aroma fills the night air. This image was turned on its side to present more effectively. It grows on the photographer’s front porch in South Carolina.
