Benton County is home to a variety of invasive weeds that cause problems in agricultural fields and conservation land.
Common Mullein
Verbascum thapsus
Miscanthus Spp.
White Sweet Clover
Melitotus alba
Wild Parsnip
Pastinaca sativa Wild parsnip is a biennial plant that begins as a small rosette and sends up large yellow flowers and goes to seed the second year. It was brought over from Europe and Asia to be planted in gardens so the root could be eaten. The plant escaped the gardens and has become an invasive weed, growing wherever it can and spreading quickly once established.
