Allium spirale
Allium spirale, also known as Korean aging chive, is a plant species native to Korea, Primorye, and parts of China. It is cultivated in many other regions and has for some reason obtained the common name German garlic. Other common names include spiral onion, corkscrew onion, and curly chives.

Leaves are flat, long and narrow, shorter than the scape but only about 5 mm across, generally twisted in a helical fashion. Umbel is hemispheric, densely crowded with many flowers. Tepals pink with a dark red midvein. It
