I had one of these pop up in my flower garden, had never seen one, researched it and found out it is Flower
Of The Hour, it only blooms once and does not last but a short time in the day...sometimes you would see
one, sometimes you would miss the one that bloomed that day, very pretty, hope they reappear this
season as well, had you ever heard of this flower?, I never had!

I thought it looked like a hibiscus.

If you Google Flower Of The Hour it looks just like this! What a surprise plant, and it does only bloom 1 time only for
a short duration, I read all about it and found it interesting for sure!

Hibiscus trionum. Several photos in the ATP database. I love reading about new things!

Flower of an Hour (Hibiscus trionum)

Donald and Seedfork, how right you are, , now I know more about it, thanks for responding!

It can be invasive in the garden as it self seeds prolifically.
Nevertheless, it is pretty neat, especially the translucent seed pod.

this was a informative site, I Googled it to see if there was a chance I would see them reappear, and it is likely as it said the reseed themselves.
I am hoping to see them again.
