The 'Billion Stars' Astrantia (also known by the cultivar name 'Star of Billion') is a delicate and intricate cut flower highly valued in floristry for its unique appearance, long vase life, and versatility.
Appearance: The flower heads resemble tiny, dome-shaped "pincushions" made of a cluster of minute flowers, surrounded by an elegant, star-like ruff of papery, white bracts that are often tipped with green.
Color Transition: The blooms have a dynamic coloration, often opening as pale green, developing a subtle pinkish blush as they mature, and eventually fading to a crisp white.
