Look closely, and you will see two Spicebush Swallowtails, two male Eastern Tiger Swallowtails and one female Eastern Tiger Swallowtail for a total of five! This buttonbush was the biggest butterfly magnet on the preserve that day. EVERY time that I passed it, there were swallowtails nectaring, along with the usual assortment of bees and other pollinators. If you have a wet spot on your property, and you want something to attract butterflies and bees, you should consider planting a buttonbush.
