Species Details

Hemlock is a poisonous native biennial of streamsides, waysides, waste ground and wet open woods. It is frequent throughout the eastern and southern parts of our area as at Ashbourne (SK1746), Catton (SK2014), Weston-on-Trent (SK4127), Steetley Quarry (SK5476) and Killamarsh (SK4480). Elsewhere it is rare or virtually absent as in the Dark Peak. Clapham (1969) records it as “Locally frequent, especially in the south of the county” and it thus appears to have spread through the north-eastern corner of the county in the last 40 years or so. Some authorities consider it an ancient introduction to our area (Stace XXet al. 2003).
