Canada Thistle
Cirsium arvense* /Aster Family
(INN) Rank 2

Honeybees and bumblebees get a lot of bang for their buck on thistles. Being a composite flower, there are hundreds of tiny florets per plant, each one containing a nectar reward. According to my Wildflowers of Tennessee book, Canada Thistles are rare in Tennessee and only found in Knox and Johnson counties in east TN and Davidson county in middle TN. Now Anderson county can be added to the list! I found these blooming in Oak Ridge on South Illinois Ave. in early June. It was with this flower that I met my numerical goal for this website, it was plant #500!
Perennial
Where seen: Oak Ridge, Great Smoky Mountains NP, Warriors' Path SP
