Spotted Knapweed wildflowers, a member of the Aster Family,  are growing profusely here on Cape Cod. Even though they are a pretty and unique wildflower, they are considered invasive in some states.

Spotted Knapweed has a 1″ thistle-like head with forked outer rays and black-tipped bracts. Their many-branched stems are hairy and wiry.  They grow in July and August along fields and roadsides. I took this photograph along one of the trail at Fort Hill.

Have you ever seen a Spotted Knapweed?
