At this time of year Buttonbush (Cephalanthus occidentalis) is studded with one-inch diameter white or pale pink globular flowerheads. Each “button” consists of many individual flowers, each of which has an extended pistil, giving the flowerhead a starburst appearance, and a striking resemblance to a pin cushion. Bees, hummingbirds and butterflies all flock to this bountiful nectar provider. Once seeds have formed, waterfowl and shorebirds feed on them. Often found near swamps and wetlands, Buttonbush’s mid-summer flowering period lasts for about a month.
