Kendall County (IL) Forest Preserve District Common
Teasel (Fuller's
Teasel) The non-native (European) Teasel is common (unfortunately) in our area. It is an invasive that is found along busy highways where seeds have been scattered by vehicles and it keeps trying to move in to our natural areas. It is a biennial with a low rosette of basal leaves, up to 12" long and 3" across, in the 1st year. In the 2nd year, it develops stems up to 6' tall with crinkly lance-shaped untoothed opposite leaves up to 12" long and 3" across. The tall flowering stalk terminates in a stout spike of flowers up to 4" long and 1½" across with several linear bracts up to 6" long curving up around the spike. The narrow ½" long tubular flowers are pale lavender or white and densely crowded together all around the spike giving it a pincushion-like appearance after the flowers have withered away.
