It is called Jewels of Opar or Talinum. I have some in my garden as well. They are a reseeding annual and bloom for months.
Yep that's what they are alright,, I have them too,, However mine come back from the
seeds dropping IF I could just get them all to drop in the same place it would look alot better,,
BTW Skippy I like that your's are potted up,, it looks very nice,, and great close up pictures!
