Leeks

Concise Bible Dictionary:

 
Leek Field
The Hebrew word seems to refer to what is “green,” and is often translated “grass”; twice it is rendered “hay” and once “herb,” but the leek is very likely referred to in Numbers 11:55We remember the fish, which we did eat in Egypt freely; the cucumbers, and the melons, and the leeks, and the onions, and the garlick: (Numbers 11:5). The Israelites, longed for such as they had eaten in Egypt. The Allium porrum has long been a favorite in the East. Dr. Kitto preferred the Trigonella foerum graecum, a grass similar to clover.
