Kendall County (IL) Forest Preserve District Tall Hedge
Mustard (Small
Tumbleweed Mustard) The non-native (European) Tall Hedge Mustard is uncommon in our area. It prefers full sun and medium to dry moisture in disturbed soil. Habitats include waste areas, fields and roadsides. This annual or biennial weed is 2-4' tall with a stout central stem covered with hairs and branching in the upper half. The lower leaves are up to 6" long and 2½" wide, on stalks up to 2" long, and are deeply divided into narrow to angular lobes, the tip lobe largest and triangular-shaped, with 2 to 4 pairs of lateral lobes that often point backwards. Leaf surfaces are variously hairy with irregular, coarsely toothed margins. Small densely packed rounded clusters of yellow flowers occur at the end of the branching stems. Each flower is about 1/3" across with 4 rounded bright yellow petals.
