Allium caesium explained

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 NaNm (-2,147,483,648feet).[1]

Allium caesium is typically about NaNcm (-2,147,483,648inches) tall, and grows best in full sun to partial shade.[2] It produces round bulbs up to 15 mm across. The scapes are up to 65cm (26inches) tall. The leaves are round in cross-section, and slightly shorter than the scapes. The flowers are sky-blue.[1] [3] [4] They typically appear in the summer (June to August in England) and attract pollinators such as bees and butterflies.[5] The Latin specific epithet caesium means "grey-blue".[6]

In cultivation in the UK, this plant has gained the Royal Horticultural Society's Award of Garden Merit.[7] In the US it is suitable for hardiness zones 4-7.[8]
