Allium siculum, also known as Sicilian honey lily, Sicilian honey garlic, or Mediterranean bells, is a perennial, ornamental, bulbous plant in the genus Allium used in gardening. It is a member of a small subgenus Nectaroscordum of Allium, which consists of only this species and Allium tripedale.[3]

Habitat and Description[edit]

Allium siculum is native to Asia Minor, southern France, mainland Italy (Basilicata, Abruzzo, Umbria, Toscana),[4] Sardinia, Corsica, Bulgaria, and Sicily, growing in damp, shady woods. It has showy clusters of gracefully drooping bell-shaped blossoms produced in May to early June sitting atop a tall green stem, to 1.2 m in height. The florets (blossoms), suspended on long drooping pedicels, are cream colored with a maroon streak down each petal, have white flared tips, and are tinted green at the base. The blossoms are followed by decorative, erect seed pods in late summer. The blue-gray foliage is triangular in cross-section and strongly twisting along the length of the ascending leaves.[5][6] A penetrating, skunky odor is released when the plant is cut.

Uses[edit]

Said to be deer resistant, Allium siculum is used as a seasoning in Bulgaria. It is rather commonly used in gardens because of the showy, drooping blossoms and unusual foliage.[citation needed]

Properties[edit]

When Allium siculum is crushed, lachrymatory agent (Z)-butanethial S-oxide along with several 1-butenyl thiosulfinates are detected by mass spectrometry using a DART ion source. (Z)-Butanethial S-oxide (the higher homolog of syn-propanethial-S-oxide, the onion lachrymatory agent) isolated from the plant was shown to be identical to a synthetic sample. The precursor to the lachrymatory compound, (RS,RC)-(E)-S-(1-butenyl)cysteine S-oxide (homoisoalliin), was isolated from homogenates of A. siculum, and a closely related species, Allium tripedale, and fully characterized.[7][8]
