The achillea you reach for when you want the romance of gypsophila with the reliability of a hardy perennial. Ballerina produces clouds of pure white, double button flowers held on neat, self-supporting stems — bred from our native sneezewort but selected for a tidier, bushier habit that shrugs off summer downpours without flopping.Genuinely self-supporting at 40–60cm, long-flowering, and beautiful both fresh and dried. A quiet workhorse that earns its place in the border every single year.
