Kale, considered leaf cabbage, and are grown for their leaves, so we can eat them. They are good, do you like?
I do not like the taste of kale by itself, but I can eat it combined with other things
Kale can be green or purple, and the main part doesn't have a head. I think the leaves are attractive in a salad.
The are nice looking, I agree.  I like to add them on sandwiches or mix them with eggs.  
Kale is closely associated to cabbage, more than lettuce. 
I see.  Well, I do enjoy cabbage quite a bit.
It's funny, but back in the middle ages, Kale was the most common green veggie in Europe.
I did not know that.  Now it is considered more of an upscale veggie.
