Bracts
HedgeparsleyHedgeparsley CharacteristicsCharacteristics
Biennial that can also act like an annual; 2-3’ tall
Freely branching form
Stems and leaves have short hairs present
Flowers bloom for about 2 weeks
Small umbels; alternate leaves
Taproot
Seeds are covered with velcro-like hairs; Latches on to hair, fur, clothing, etc.
Mainly seen invading roadsides, ROW, and woodland edges
Rosettes look very similar to Queen Anne’s-lace and young Herb Robert (Geranium robertianum). Leaves also look similar to those of wild chervil

Poison hemlock CharacteristicsPoison hemlock CharacteristicsBiennial or monocarpic perennial; 4-10’ tall
Stems are hollow, ridged, and hairless; purple mottling near base
Alternate, pinnately compound leaves are hairless and shiny; broadly triangular shape; leaf veins end at the tips of the tooth margins
Taproot
Two joined seeds; ridged
Often found along roadsides, fields, stream banks, and in floodplains
Leaves look similar to wild chervil. Water hemlock (Cicuta maculate) has leaf veins that end in the notches between the tooth margins.
