This plant is in the carrot family. It is a host plant for the Eastern Black Swallowtail butterfly. A very airy looking plant which is native to AZ, AR, FL, GA, KS, LA, MS, MO, NC, SC, NM, OK, NY, NJ, VA and TX. Grows in a wide variety of soils including incredibly poor, sandy, soil. The blooms are so diminutive that it would almost require a magnifying glass to see the individuals. You can just barely see them.
At this time of year in my location the plants are dying out already. They will reseed and new plants will appear next year in the late winter.
