Practical Information

Additional Notes
Comments
After pollination, the calyces fall and the subtending, 5-lobed, leafy bracts enclose the fruits. "Four-o'clock" refers to the flowers opening in late afternoon and "umbrellawort" refers to the overhanging bracts that resemble an umbrella. Wild four-o'clock is related to bougainvillea.
Special Notes: See narrowleaf four o'clock.
