Flower profile

Create an airy framework for bouquets.

Ammi produces branching stems topped with broad lacy umbels. White Dill offers classic white filler, Green Mist adds fresh green texture, and Purple Kisses introduces rose, burgundy, and chocolate tones.

One sowing has a peak windowFor a longer cutting season, make two or three modest sowings a few weeks apart instead of relying on one large planting.

Planting

Sow where the taproot can remain undisturbed.

Direct sow in early spring as soon as soil can be worked. In mild climates, fall sowing can produce earlier, stronger plants.

01

Prepare a fine bed

Remove weeds and rake the surface level so the small seed makes good soil contact.

02

Cover lightly

Sow about ⅛–¼ inch deep and keep moisture steady through germination.

03

Thin instead of crowding

Thin established seedlings to 6–12 inches. Wider spacing encourages branching and sturdy cutting stems.

Succession cueRepeat a small sowing in 2–3 weeks for a longer harvest window.

Ongoing care

Keep tall stems open and upright

Give full sun

Use full sun for strong stems and well-shaped umbels; light afternoon shade is acceptable in hot regions.

Maintain steady moisture

Avoid sharp drought stress while plants are stretching and forming flowers.

Protect airflow

Open spacing reduces weak growth and makes harvest easier.

Support before bloom

Install netting or stakes while plants are still short so stems grow through the support.

Season checkpoints

Support the planting before it looks necessary.

Bouquet harvest

Cut when the small florets begin opening.

Cut umbels when most buds show color and the first small flowers are open. Very immature heads may wilt; overmature heads shed and lose the clean lace effect.

  1. Cut in the cool morning.
  2. Remove foliage below the water line.
  3. Condition in clean water before arranging.

Questions flower gardeners ask

Ammi growing FAQ

When should Ammi be sown?

Direct sow in cool early-spring soil; mild climates can also use fall sowing.

Does Ammi transplant well?

Direct sowing is preferred because plants develop a taproot, though young plugs can be moved carefully.

How deep should seed be planted?

Cover lightly, roughly ⅛–¼ inch, and maintain even moisture.

How far apart should plants be?

Thin to 6–12 inches depending on desired branching and stem thickness.

Does lace flower need support?

Tall plants benefit from netting or stakes, especially in exposed cutting rows.

Can I succession sow Ammi?

Yes. A second or third sowing several weeks apart extends the harvest.

When should umbels be cut?

Harvest when most buds show color and the first small florets open.

Why did cut stems wilt?

Heads may have been cut too immature or allowed to dehydrate before conditioning.

Does Ammi attract beneficial insects?

Its many small flowers are accessible to hoverflies, small wasps, and other beneficial insects.

Can Ammi sap irritate skin?

Carrot-family sap can irritate sensitive skin and react with sunlight; gloves and washing are sensible precautions.
