Thistles are flowering plants known for their sharp spines and vibrant purple blooms. They belong to the Asteraceae family and can be found in many regions around the world. Thistles often grow in fields and meadows, attracting various pollinators like bees and butterflies. Their tough nature allows them to thrive in poor soil conditions, making them resilient plants. Despite their prickly appearance, thistles have important ecological roles. They provide food and habitat for wildlife, and some species are even used in traditional medicine. Additionally, thistles are often seen as symbols of Scotland, where the Scots adopted the thistle as their national emblem.
