Green Shamrock Saint Patrick's Day Floral Art Stone Coaster

Serve your drinks on this marble stone coaster with a great Irish shamrock. Although it is not clear what species the shamrock should be, the common wood sorrel or some type of clover, I chose the former. In this case the Oxalis acetosella. I think this plant looks much better than the common clover. Tradition says that shamrock was used by Saint Patrick to teach the holy Trinity. But there is no proof of that. In any case, the shamrock became a potent symbol for Ireland. And of course I use greens for the colouring. The font is Celtic style. The word seamróg is retrieved from the internet. So it must be right!
