Allium stipitatum, Persian shallot,[4] is an Asian species of onion native to central and southwestern Asia.
[5] Allium stipitatum in the more inclusive sense occurs in Turkey, Iraq, Iran, Pakistan, Afghanistan, Turkmenistan, Tajikistan, Uzbekistan, Kyrgyzstan, and Kazakhstan.
Individual flowers, of which there are many, are a typical allium shape, with a superior ovary and six tepals of a lilac to purple colour, around 2.5 to 5 cm long; white forms are known.
[8] Mathew describes this species as "stately", and the easiest to grow of the tall alliums, flowering in about four years when grown from seed.
Davies notes that "as a bonus numerous offsets are produced";[6] this has the potential to make the species invasive when grown in borders.
Analysis of the cut plant using a mass spectrometer equipped with a DART ion source showed the presence of N-hydroxypyridine-2-thione, also known as pyrithione, a compound which is moderately cytotoxic toward human tumour cell lines, and highly active against fungi and Gram-negative bacteria.
