Wild chervil Anthriscus sylvestris L. Parsley Family Key identifying traits White flowers arranged in umbrella like cluster Fernlike compound leaves have a sheathing base Hollow, furrowed stems with lower stem hairy Nodes have a fringe of longer hairs Each ⅛ to ¼ inch white flower produces two seeds Two seeds are joined and have antennae like tips Seeds are dark, ¼ inch long, narrow, smooth, shiny Plant grows 1 to 4 feet tall and has a tap root Foliage is not aromatic Biology and ecology Biennial or short lived perennial reproduces by seed Upright rosette first year; flowers the following May through June or July Found in moist pastures, forested areas and roadsides Control Prevention – Learn to identify the plant; be careful of British wildflower seed mixes formulated to recreate the flora of hedgerows and meadows of the British Isles. Biological – None available at this time Cultural – Competitive vegetation helps but can invade well managed areas Mechanical – Cultivation generally kills plants although some can regenerate from the crowns; mowing is ineffective; digging is effective if enough of the tap root is removed Chemical – Not much solid information available at this writing. We are experimenting with various herbicides applied in the fall and spring; because it likes moist areas, options are somewhat limited. Where found – Limited acreage primarily in the northeastern portion of Stevens County, but known to be in neighboring Spokane Co and British Columbia Stevens County Noxious Weed Control Board, March 2000, Updated March 2003
