– Allium ampeloprasum L. var. hemisphaericum Sommier (1906).

Etymology –
The term Allium comes from the classical Latin allium, the etymology of which is much debated. Among the hypotheses is its derivation from the Indo-European root *ālu- bitter herb, represented, among other things, by the Sanskrit ālu Colocasia esculenta; A loanword from the Greek ἄγλις áglis (head of garlic), itself of Akkadian origin; a loanword from a southern Italic language, similar to the Greek ἀλλᾶς allàs (garlic sausage). De Vaan considers all these hypotheses unlikely and suggests a possible connection with ala ala, based on the image of the bulb divided into many wings, or segments.
The specific epithet hemisphaericum comes from the Greek prefix ἡμι- hémi- semi-, half, and from σφαιρικός sphairikós (spherical): hemispherical, shaped like a half globe, or belonging to a single hemisphere.

Geographical Distribution and Habitat –
Allium hemisphaericum is a plant endemic to the island of Lampedusa (Pelagie Islands, Sicily).
Its habitat is rocky coasts, from sea level up to 130 m above sea level.

Description –
Allium hemisphaericum is a bulbous, geophytic, perennial herbaceous plant with a stem 20–40 cm tall.
The flowers are greenish-white to purple, with long pedicels; they are clustered in hemispherical inflorescences, 3–4 cm in diameter.
Flowering occurs between June and July.
The fruit is a subglobose capsule, 3.5–4 mm in diameter.

Cultivation –
Allium hemisphaericum is a hardy species, typical of arid, stony environments. Consequently, its cultivation requires simple but specific conditions.
It requires a very sunny location.
It is adapted to Mediterranean climates, with hot, dry summers.
The soil must be well-drained, even poor and stony. It prefers calcareous soils, but it also grows in sandy soils. Avoid waterlogging.
Regarding irrigation, it is almost completely unnecessary as it is drought-resistant. However, it can only be watered after transplanting or during exceptionally dry periods.
Propagation can begin from bulbs, planted in autumn at a depth of about 5–7 cm and 10–15 cm apart.
It is a low-maintenance plant that requires no special fertilization.
It naturalizes easily if it finds favorable conditions.

Uses and Traditions –
Allium hemisphaericum, being quite rare and localized, does not have such widespread traditions of use as other Allium species. However, according to some popular customs (limited and local) in some rural areas, the bulbs were used as a flavoring similar to other wild garlics.
The leaves and bulbs were used as a condiment in small quantities.
Like many species of the Allium genus, it was considered a “protective” plant according to popular beliefs, capable of warding off negative influences.
In ethnobotanical contexts, it is valued more as a wild plant than as a food resource.
As a species of conservation interest, it is best not to collect it in the wild; in fact, the IUCN Red List, due to its restricted range, classifies Allium hemisphaericum as Vulnerable.

Preparation Method –
When cultivated, Allium hemisphaericum can be used similarly to other small wild garlics.
The bulbs can be used as a delicately flavored seasoning.
They can be lightly toasted, chopped to season vegetables, soups, or sauces, and preserved in vinegar.
The tender, fragrant leaves can be used fresh. They can be chopped raw in salads or added to hot dishes at the last minute (as an aromatic herb); mixed into omelettes or fillings.
The inflorescences are sometimes used as an edible garnish. They are slightly aromatic and excellent for decorating rustic dishes.
However, as with many wild plants, consumption should be moderate, especially for those sensitive to Alliums.
