Ammi majus, commonly known as sea foam, lace or
greater ammi, is an annual herbaceous plant of the Apiaceae family.
Native to the Mediterranean region and the Middle East, it is
characterised by its delicate white, umbrella-shaped inflorescences
(umbels) that resemble fine lace, bearing a strong visual resemblance to
the wild carrot. It grows to heights of between 20 and 100 cm
(occasionally up to 1.5 metres), with erect, branched stems and bright
green, divided leaves. It flowers from mid-spring to late summer (May
to September), attracting pollinators such as bees and butterflies in
abundance. It grows wild as a ruderal plant in cultivated fields,
along roadsides and on disturbed land (acting as a weed in some
regions). It is a favourite filler plant for florists and landscape
designers. Its umbels lend a rustic air to arrangements, and its cut
flowers can last up to two weeks in a vase. Its extracts contain
substances called psoralens (such as xanthotoxin), which have
historically been used in medical treatments for vitiligo, helping to
resynthesise epidermal melanin through controlled exposure to sunlight.
The plant’s sap contains furocoumarins. If it comes into contact with
the skin and the skin is then exposed to sunlight, it can cause severe
dermatitis and burns. It is recommended that gloves are always worn when
handling the plant.
