Suggested varieties

Popular varieties of Ammi to consider

Graceland

A reliable Ammi majus with large, white, lace-like umbels on tall, sturdy stems. It is vigorous and copes well with UK's cool summers, making it a top choice for cutting and borders.

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.
