Allium caesium, light blue garlic, is a species of herbaceous perennial flowering plant native to central Asia (Xinjiang, Kazakhstan, Kyrgyzstan, Tajikistan, Uzbekistan). It grows in deserts and dry fields at elevations of 700–2000 m.[2]

Allium caesium produces round bulbs up to 15 mm across. Scapes are up to 65 cm tall. Leaves are round in cross-section, slightly shorter than the scapes. Flowers are sky-blue.[2][3][4] The Latin specific epithet caesium means “grey-blue”.[5]

In cultivation in the UK, this plant has gained the Royal Horticultural Society’s Award of Garden Merit.[6]
