Cirsium arvense Fact Sheet
Differs from other species of the true thistle in that there are male and female flower heads, and these are on separate plants. By asexual reproduction, it is possible that a colony of male plants would produce no fruits, but still maintain itself. Flowering occurs during July and August.
