Help! What are these lovely flowering plants?

Having recently moved to our Little Cabin by the creek, I recently noticed these growing prolificlay on the banks of the Sweet little creek that runs behind our home. Seeing the thorns, I first thought I had somehow been blessed with Bougainvillea! But, as I am in Southern Missouri, I donโ€™t believe it is that Stunning plant that I fell in love with in South Texas years ago.
The bees ๐Ÿ see to Love ๐Ÿ’• them! Can someone please tell me what they are?
Thank you Fellow Home Talkers!
