I love Kale but it is just leaf cabbage
Really? I heard it was nutritious
A kale plant has green or purple leaves depending on the type
Kale originated in the eastern Mediterranean and Asia Minor, where it was cultivated for food beginning by 2000 B.C.
Kales are considered to be closer to wild cabbage than most other forms 
oh ok I read that The earliest record of cabbages in western Europe is of hard-heading cabbage in the 13th century
That is true "Kale" bears semblance to "kail", a variant of "cawul" from Scotland
