About

The sand leek (Allium scorodoprasum), also known as rocambole and Korean pickled-peel garlic, is a Eurasian species of wild onion with a native range extending across much of Europe, Middle East, and Korea.

The species should not be confused with rocambole garlic, which is A. sativum var. ophioscorodon.

How to grow it

A. scorodoprasum is edible, but rarely cultivated, and has a shorter flower stalk and fewer and more inconsistently shaped cloves than Rocambole garlic. Sand leek also has a dark violet bulb wrapper.

Elephant garlic (properly A. ampeloprasum var. ampeloprasum) is also sometimes incorrectly sold as A. scorodoprasum.

Where it grows

The natural habitat of A. scorodoprasum is damp broad-leaved woodland, forest margins, shores, hillside meadows and hedgerows. It was at one time used as a kitchen herb and can occasionally be found near old habitations.

Uses

The bulbs and flower bulbils can be cooked similar to garlic, with a milder flavor.
