About Allium spirale Schweigg.
Allium spirale, commonly called Korean aging chive, is a plant species native to Korea, Primorye, and parts of China. It is cultivated in many other regions, and is also widely known by the additional common name German garlic. Its other common names are spiral onion, corkscrew onion, and curly chives. This species grows in clusters of narrow bulbs, each reaching up to 15 mm in diameter. Its scapes can grow up to 40 cm tall. The leaves are flat, long and narrow, shorter than the scape, and only around 5 mm across; they are generally twisted in a helical shape. Its inflorescence is a hemispheric umbel, densely packed with many flowers. The tepals are pink with a dark red midvein. Allium spirale most commonly grows on dry slopes, in loess and steppes, and in areas with large amounts of sand, gravel, or stone.
