This is one of the best non-season-specific centerpiece ideas I’ve come across.  Leave it to Martha to post this picture of a beautiful baby boxwood in a perfectly appointed bucket as a  summer wedding centerpiece.  Not only eco-friendly and re-purposeful after the wedding by planting it but the green tree can be the stage on which to set your own colors and decor.

I would add twinkle lights for a Holiday or evening wedding (battery operated of course).
