Grows up to half a metre in length.

Does not form a full 4π steradian globular cluster, but rather less than a hemisphere, perhaps only π steradians.

With six white petals (actually tepals), and unusually, not arranged in two rows of three partially over-lapping tepals typical of many garlics, but in a six-sided star similar to those of some other white-flowered Garlics Ramsons (Allium ursinum) and Hairy Garlic (Allium subhirsutum).

Six stamens shorter than the tepals. A central green central ovary expands as the flower matures.

Pollen is yellow-coloured; anthers that have lost their pollen are fawn-coloured, becoming grey. the central fruit enlarges as the tepals drop off (central lower).

Leaves are long and linear and keeled for stiffness. The flower stems are isosceles triangle in cross-section.


Many similarities to : Hairy Garlic (Allium subhirsutum) which also has white flowers but that has a round stem (rather than isosceles triangular) that is also hairy, and the leaves are not folded as much lengthways (keeled).

Slight resemblance to : Ramsons (Allium ursinum) but that is much shorter and has broad lanceolate leaves rather than long linear ones.

A garden plant that sometimes escapes into the wild mainly in the South of the UK. It is native to Southern Europe including Italy (Naples); it is also native to South Africa.

The above photos possibly correspond to one of the garden sub-species, such as Allium neapolitanum ssp. philippi or Allium neapolitanum ssp. grandiflorum which are probably taller than the half-metre of Allium neapolitanum itself.
