Ammi majus. Also known as False Queen Anne’s Lace. This graceful annual produces an ephemeral cloud of lacy white flower heads above an upright column of ferny, dark green foliage. A. majus is one of the most attractive flowers to beneficial insects and pollinators. A continuous parade of bees and butterflies will visit the flowers. Uniform growth from a central stem and few branches make it easy to harvest for bouquets and arrangements. The 50cm (20″) tall plants look wonderful in large plantings and borders. Note that this plant is botanically different from true Queen Anne’s Lace, so there is no risk of cross-pollination with your carrot crop.
