Day 3 with the penny in the tulip vase and everything looks beautiful! No wilting or browning on pedals, just a group of gorgeous blooms. Mrs. LTB did make a brief amendment to the penny tip as apparently the older the penny the better (mine looked too shiny to her). This makes perfect sense as it is said that it is the copper that is responsible for the anti bacterial properties and the older the penny the higher the copper content.
Below is also Day 3.
Day 4 and still looking great. Sorry for the photo...sadly I took this picture well after the sun went down so the artificial light seriously strips the ability to see these beauties clearly.
