I gave the morning glory vines that are growing in a pot in my office a bamboo pole to climb a few weeks ago. There is about four feet (1.2 m) for them to climb, and two vines have already reached the top.
There are about a half dozen morning glory plants growing in the pot. Together, they produce two or three flowers every day.
These two flowers were growing on two different vines. There was a third flower blooming above them.
