Ammi majus Seeds

Ammi majus is a robust Hardy Annual. It holds the prestigious RHS Award of Garden Merit, a mark of excellence for its reliable garden performance and significant contribution to floral design. Biologically, it is a quintessential "umbellifer," possessing flat-topped flower heads (umbels) composed of hundreds of individual florets.

The "False Lace" Biology: While it resembles the wild carrot (Daucus carota), Ammi majus is a distinct species native to the Mediterranean. It is a "cool-season" annual, which allows it to be autumn-sown to develop a deep, resilient root system over winter, leading to significantly taller and more prolific flower heads the following spring.

Beneficial Insects: Beyond its beauty, Ammi is a powerhouse for biodiversity. The flat landing platforms of its umbels are an exceptional resource for British hoverflies and tiny solitary wasps. These insects provide natural pest control by preying on aphids, making Ammi an essential component of an organic garden ecosystem.

Ammi has a significant taproot and highly resents root disturbance; for this reason, direct sowing or deep modules are the most reliable methods for success.

How to Sow:
Direct sow outdoors from March to May, or in September/October for significantly taller, stronger plants the following summer. The seeds are minute; scatter them thinly and cover with only a "whisper" of soil (3mm). They require some light to trigger germination. Germination typically occurs within 7-21 days.

Where to Plant:
They demand full sun to reach their peak flowering potential and thrive in moderately rich, well-drained soil. They are specialists of mid-to-back border positions. Space plants 30cm apart. Crucial: Because Ammi can exceed 1m in height, sturdy support such as horizontal netting or pea sticks is essential to prevent the slender stems from collapsing during summer rainfall.

Ongoing Care:
Keep the soil moist until established. Ammi is a prolific "cut-and-come-again" species; the more you harvest the lacy heads for the vase, the more the plant will respond by producing fresh side shoots, ensuring a continuous supply of white lace until the first autumn frosts.
