Cube vases for booth tables and birdhouse tables. Orange pincushion protea shown here - we could use that or orange lily or orange gerbera daisies. We could put rock in the vase as shown or go with teal water or twisted teal wire or teal gemstones
Horsetail and creeping jenny - very compatible, they both like it wet. This kind of plant combination is fairly easy to maintain because it doesn't need a drain hole in pot, you can fill it with many days worth of water, even in hot weather.
