Where I can find cabbage on survival?

Hello guys,
Where I can find cabbage? Me and my mate are playing survival and we didn't see any cabbage yet. Please help us

 

You're likely tripping over it and not knowing it.

Turn off grass in the graphics settings and then you'll see everything you can pick up. Once you're used to what everything looks like, turn the setting back to what you prefer.

 

Found that they start spawning after a day or so in the game. Look in the open areas. Found a batch of 21 all growing together. Funny bit was that a few days after harvesting all they respawned. I had dug up the ground as there was iron below it so now the plants is floating.

 

I found it useful to go into 3rd person, "V" key (so you're looking at the back of your characters head) hold down "Alt" and mouse wheel out a bit, then look pretty much straight down while out in the grasslands. Cabbages more readily seen this way, though they'll still have to be pretty darn close.
Also, now that they're findable in clusters, putting down a marker block can be helpful to harvest them again once they regrow.
(btw, I've only played single player survival, so no idea how claim blocks work; maybe you can't put down marker blocks if in other game types?)

Edit: by marker block I just mean anything handy; wooden wall, the small stone column, etc., something you can see at a distance.
