Flower Frogs are a great way to get a lot out of just a few stems. They are used along with a standard mason jar. Each flower frog is approx. 3.25" in diameter. Just fill the jar with water, position the frog on top, add fresh flowers through the holes.
They make great gifts! (Also see the larger "Bullfrogs" that are 4" diameter and fit over wide-mouth mason jars).
