Allium schoenoprasum — wild chives

Copyright: various copyright holders. To reuse an image, please click it to see who you will need to contact.

Facts

Wild chives is native in North America, but it has also escaped from cultivation, making it difficult to separate the native populations from the escaped ones. In New England, native populations tend to inhabit river shores and meadows, while the introduced populations favor fields, roadsides and vacant lots. Native Americans have long used the bulbs and leaves for flavoring foods such as fish, soups and salads.

Habitat

Anthropogenic (man-made or disturbed habitats), floodplain (river or stream floodplains), meadows and fields, ridges or ledges, shores of rivers or lakes

5.  Allium schoenoprasum L. n

wild chives. Allium schoenoprasum L. var. laurentianum Fern.; A. schoenoprasum L. ssp. sibiricum (L.) Čelak.; A. schoenoprasum L. var. sibiricum (L.) Hartman; A. sibiricum L. 
• CT, MA, ME, NH, RI, VT. River banks, shoreline outcrops, meadows (native populations), fields, roadsides, and vacant lots (non-native populations). Allium schoenoprasum includes 
both native and non-native races in New England. Non-native plants often have ovate to narrow-ovate, merely pointed outer tepals and leaf blades equaling or overtopping the 
scape, whereas native plants often have lanceolate to narrow-lanceolate and sharply pointed outer tepals and leaf blades shorter than the scape. However, such differences have been shown to be clinal and are not reliable for discriminating taxa (McNeal and Jacobsen 2002). Therefore, infraspecific taxa are not recognized here.
