An upright, monocarpic (meaning it will generally flower once then die) umbellifer to around 80cm, with aromatic, soft, ferny blue-grey foliage. In summer, upright, branching stems bear flattened umbels of tiny, lacy white flowers which can be used in flower arrangements. An ideal choice for a sunny gravel garden
