What is torch thistles?

Torch thistles (Cirsium rivulare) are ornamental plants that belong to the Asteraceae family. They are native to Europe, but have become popular garden plants in many parts of the world due to their distinctive appearance. Torch thistles are herbaceous perennials that typically grow between 2 and 4 feet tall and 1 to 2 feet wide. The plant has a strong upright stem covered in spiny leaves and produces striking crimson-purple, thistle-like flowers that bloom from late spring to midsummer. Torch thistles are deer resistant and drought tolerant, making them a popular choice for gardeners looking for low-maintenance plants. They prefer full sun and well-drained soil, but can tolerate nutrient-poor soils. Torch thistles can be propagated by seed or by dividing mature plants in the spring.
