Handmade by Canadian artisans, our stoneware puddler attracts butterflies to the garden. In the puddler's shallow well of recycled glass, place sand (included) or rock salt along with a teaspoon of water. When the water evaporates, butterflies are attracted to the minerals left behind from the water and sand/salt. Refill with water (and perhaps a pinch of salt) to lure butterflies to return regularly.
