And Ammi, Which Is Usually What You Are Buying
Queen Anne's lace is a flat white umbel made of hundreds of tiny flowers, held on a fine stem above ferny foliage, giving the airy meadow haze that loose modern bouquets are built around. Two plants are sold under the name: the wild Daucus carota, and Ammi majus, grown commercially and sold as false Queen Anne's lace. If you bought it from a florist, it was almost certainly ammi.
The wild plant has a small dark red floret at the centre of the umbel, said to be a drop of Queen Anne's blood from a pricked finger. Ammi does not. It is the quickest way to tell them apart.
The classic; both species
Ammi visnaga, denser and greener
The single red floret on true Daucus
Dara; a deep burgundy cultivated Daucus
False Queen Anne's lace; the commercial cut flower
Denser, greener, stiffer umbels
True Queen Anne's lace, wild carrot
A cultivated Daucus in deep burgundy and pink
Hollow stems foul water quickly.
The ferny leaves rot fast.
Buy umbels fully open; buds rarely develop.
The sap causes sun-triggered skin burns.
Buy umbels that are fully open and flat, because unopened heads often fail to develop after cutting. The individual florets should be bright white rather than dull or browning, and the stem firm and hollow-crisp rather than soft. Strip and discard the ferny foliage, which rots fast and fouls the water. Look at the centre of the umbel: a single dark red floret means you have true Daucus rather than ammi, which is worth knowing but does not change the price.
Early to midsummer for the commercial ammi crop, with the wild plant flowering roadside through the same period. It is inexpensive and largely a local grower's flower, though ammi is farmed at scale in Europe and reaches wholesalers reliably. Wedding demand for the loose meadow style is what firms up the summer price. Dara, the burgundy cultivated form, costs noticeably more than plain white.
Baby's breath gives volume in a denser, less structured way. Nigella provides similar airiness with blue flowers and better pods. Orlaya is the refined alternative, smaller and whiter, and is increasingly grown for cutting. Achillea 'The Pearl' gives flat white heads that last far longer. For the specific flat lace umbel, ammi and orlaya are effectively the only options.
This one needs care on two fronts. **The sap causes phytophotodermatitis**: get it on your skin, then expose that skin to sunlight, and you get blistering burns that can leave marks for months. Wear gloves and long sleeves when cutting quantities in sunshine. **And the family contains lethal lookalikes.** Poison hemlock and water hemlock resemble Queen Anne's lace closely enough that people have died foraging. Never gather white umbels from the wild unless you can identify them with certainty. The plants are also mildly toxic to pets.
One tiny dark red floret in the middle of the umbel means true Queen Anne's lace, Daucus carota. No dot means ammi, which is what most florists sell. It is the fastest identification there is.
The sap plus sunlight causes serious blistering burns. This is a genuine hazard for anyone cutting it in quantity on a summer day, not a theoretical one.
Hemlock looks similar and is lethal. This family has killed foragers. Buy it or grow it from known seed.
Not botanically, but they are sold interchangeably. True Queen Anne's lace is Daucus carota, the wild carrot. Ammi majus is a different plant grown commercially and sold as false Queen Anne's lace. Almost all florist stock is ammi.
A single dark red or purple floret at the centre of the umbel, found on true Daucus carota. Folklore says it is a drop of Queen Anne's blood from a pricked finger. Ammi does not have it, which makes it a reliable way to tell the two apart.
The sap causes phytophotodermatitis, blistering burns triggered by sunlight on exposed skin, so wear gloves. More seriously, poison hemlock and water hemlock look similar and are lethal. Never gather white umbels from the wild without certain identification.
