Known Plants Used For Camo?

So i have a raised flowerbed in my yard with 3 sprouts. There's about 4 feet of empty dirt between them and what i need is another kind of plant that would make it less than obvious that theres 3 plants growin. I've heard of tomato plants n stuff but i'm looking to go a step further as far as camoflauge is concerned.

I've heard beans grow as a vine and also replenish the soil in which they grow with nitrogen. Is it a good idea for a vine to be growing all up in my sweet sweet candy bushes?

Anyway if i can't find a good solution i'll just uproot them and plant them out in a abandoned field somewhere. I've already scattered about 200 seeds in a field next to this golf course. I could care less if i harvest anything out of these, i simply take pleasure in knowing one of Gods finer creations will be growing naturally throughout as it rightfully should.

Id love an answer to this one as well. I'd like to put a few in a spot and I'm more worried about helicopters spotting tilled ground in a thicket than anything else. They fly around where I come from. Do they fly looking for the stuff in other states? I know that in Ky, Ohio, and WV they do. I would like to find something that will camouflage the soil between plants that wont rob the nutrients and water from the others. Any Ideas out there?
