The plant forms dense clusters of thistle-like silvery-green foliage, and by mid to late summer, tall white flower stems emerge, showcasing stunning spiky, ball-shaped flowers in lavender-blue, each roughly the size of a golf ball. These flowers are perfect for cutting, whether for fresh arrangements or drying, and they also make a striking addition to any garden. Additionally, this plant is excellent for attracting butterflies. Once established, it is drought-resistant and thrives best in full sun.
