White clover (often called Dutch clover) is a Eurasian species that has become widely naturalized in North America. Our clover "crop" seems especially abundant this year, in part due to the fact that we do not use herbicides or pesticides on our lawn.
A perennial, white clover forms extensive root systems which may remain viable for 100 years or more. Beyond its role in adorning lawns (and providing material for clover chains), this wildflower attracts a wide variety of bees and butterflies and is consumed by most mammalian herbivores (especially cottontails). Humans also partake of the stems, leaves and flowers, using them in salads and soups or as garnishes for a variety of foods.
Sitting on our front porch this afternoon, I watched honeybees as they foraged across the floral carpet. Unlike some suburbanites, we are pleased to have a healthy clover crop.
