Chapman's Hairyjoint Meadow Parsnip - Thaspium chapmanii

Hairyjoint meadow parsnip (Thaspium chapmanii is not found in Florida, but occurs just noth of the state line in Georgia.  The two native meadow parsnips - purple meadow parsnip (T. trifoliatum) has been reported in 5 counties in the central panhandle (in and around Torreya State Park), and T. barbinode has only been documented in Jackson County in Florida.  This species occurs throughout much of eastern North America, north to Ontario, Canada.  It is a member of the carrot family (Apiaceae) and it exhibits the foliage and umbelliferous flower heads distinctive to this family. This species closely resembles, T. barbinode, but is taller and has cream-colored flowers instead of white. I have written about T. barbinode eslewhere in this blog


  1. Interesting plant. Our Ontario Provincial ministry responsible for rare species tracks this one. It turns out that "Most Ontario reports of T. barbinode appear to be T. chapmanii species (B. Wofford, pers. comm.), though material from Niagara R.M. appears to be T. barbinode". T. barbinode is described here as a "southern and eastern" plant, and it is not common at all in the Ottawa Valley.

    1. Interesting - thanks for sharing this. As you can see, it is at its very southernmost part of its range in north Florida. Where I'm growing it in my yard is several hundred miles south of its natural range.
