Bring gifts like garden tools, gloves, a kneeling pad, a package of bulbs, a gardening book. Have it outside, serve salads in big clay pots, send the guests home with tiny flowers growing in those precious little 2-inch pots. The cleanup will be a snap—everyone can wear overalls or work clothes. Why not have it at an Arboretum? The ideal invitation would be to send one gardening glove with a hand-shaped invitation inside—guests have to show up to get the other half of their glove as a set! Paint nail polish on the “hand” inside the glove!
