Habitat & Cultivation:
Thought to have originated in areas around the Mediterranean Sea and possibly regions of India, milk thistle is now found growing wild in most parts of the world with moderate temperatures, including Canada, Europe, and the United States. Because it spreads rapidly, grows in marginal areas such as vacant lots, and crowds out other plants. Most milk thistle is sourced from the Pacific Northwest, though it’s native to the Mediterranean region and southwestern Europe. According to Mountain Rose Herbs, milk thistle “is considered a noxious weed in several states, particularly in the Pacific Northwest in states such as Washington,”
