Thistles are flowering plants belonging to the family Asteraceae. They are known for their spiky leaves and vibrant purple or pink flowers. Thistles can be found in various habitats, including fields, meadows, and roadsides, and they often thrive in poor soil conditions.
These plants are important for wildlife, providing nectar for pollinators like bees and butterflies. Some thistle species, such as the Scotch thistle, are considered invasive in certain regions, as they can outcompete native plants and disrupt local ecosystems.
