Species: Allium cepa var. aggregatum
The Shallot, Allium cepa var. aggregatum, belongs to the large Liliaceae family, like the onion, with which it has numerous characteristics in common, so much so that people often get them confused.
It has been used since ancient times and, in all probability, is native to the Middle East. Nowadays it is commonly grown worldwide.
The shallot is a bulbous perennial. Flowering varieties are extremely rare, therefore in the majority of cases the species is not spread by seed dispersal but through vegetative propagation.
The bulb consists of a thin disk, which is in fact the stem, from which fasciculate roots grow downwards (to a depth of around 15 cm) and a bud – from which the leaves grow - develops. The bud is covered in layers of tissue that overlap each other concentrically. These layers (called cataphylls or bulb scales) are thick and juicy in the inner part of the bulb, and thin and dry in the outer part. The inner cataphylls form a reserve of nourishing substances that permit the real leaves to sprout, while the thin dry layers protect the bulb.
According to the variety, shallot bulbs can be compound, that is to say made up of more than one small bulb, they are of a tapered shape and can be of various sizes and have different external colours (purple, red, yellow and white, in various shades).
The aerial part of the plant is formed by leaves that are about 30 cm in length, long and thin, dull green in colour and hollow.
The cultivation cycle is annual and has a duration, according to the variety, of 4-5 months.
