Purple thistle (Cirsium horridulum)
Click on terms for botanical definitions. View as a PDF
Thistles have a bad reputation for their spiny personality, but these formidable wildflowers shine as favorite nectar and host plants for many bees and butterflies, including swallowtails. Purple thistle (Cirsium horridulum) is a larval host for the Little metalmark (Calephelis virginiensis) and Painted lady (Vanessa cardui) butterflies. The seeds are an important food source for seed-eating birds. Purple thistle occurs naturally in pinelands and prairies; it is common along roadsides and in disturbed habitats. It typically blooms in summer and fall but may bloom year-round.
