Suggested varieties
Popular varieties of Ammi to consider
Casablanca
A compact, early-flowering Ammi majus that stays shorter than most, so it suits smaller gardens and windy spots. The clean white flowers appear for weeks and are excellent for picking.
Green Mist
This Ammi visnaga variety produces soft green umbels that add a frothy, airy texture to beds and bouquets. It is tough, self-seeds readily, and handles damp British summers without flopping.
Snowflake
A fine-textured Ammi majus with delicate foliage and abundant white blooms. It is slightly more compact and bushy than 'Graceland', making it a good middle-of-border filler that stands up well to rain.
