Botanical Profile of Blessed Thistle: Structure, Growth, and Habitat
Blessed Thistle is a member of the Asteraceae family, which also includes daisies, sunflowers, and asters. This resilient plant is easily identifiable by its tall, slender stems that can reach heights of up to 3 feet. The leaves are deeply lobed and form a rosette at the base, providing a lush, green backdrop to the vibrant purple flower heads that bloom from midsummer to early fall.
Growth Patterns and Lifespan
Blessed Thistle thrives in well-drained soils with a neutral to slightly acidic pH. It prefers full sun but can tolerate partial shade, making it versatile for various garden settings.
