Our polyresin hand painted puddling stone is a beautiful way to create your own mineral puddle to attract beautiful butterflies to your garden. The recessed blue well holds sand or rock salt and a teaspoon of water. When the water evaporates (in under a day), butterflies are attracted to the crystal mixture left behind. Once they know where they can find the delicious treat, they return regularly. Placing pieces of overripe fruit on the stone is another way to attract butterflies. Complements any sunny garden area. Measures 9-3/8" x 5-1/4" x 1/2".
