I am more and more convinced that the Moon Flower that I have come to love this last few years, is,indeed, closer to being a WEED than not. It looks like the Gymsum weed and it's seed pods are identical so it has to be close kin.The horrible drought we are having this year,has had no effect on it.It is thriving as is the Bermuda grass. I guess if we lived in the desert, those two would definitely be the plants to grow.
While researching the Moon Flower, I found there are a few different ones. I'm not real sure which one I have, but it does open at night. It begins to open each evening around 7 pm, but is not fully open until much later. I took pictures at regular intervals, and at 9 pm, it still was not as fully open as it was this morning at daybreak. Which ever type I do have, I love it. I am willing to share seeds if anyone is interested. They are plentiful. I try to keep some of the seed pods cut off,helping it to bloom longer, but there are always lots of seed pods that have been overlooked come the end of the season. With all of the plants that come up each year on their own,it would be impossible to clip all of the seed pods.
