Told the wife one time that, "Most people are blind to it in plain sight..."
Try and hide it and they find it right away..
we have a deck on the back of the house. The fire pit is down from that about 15 yards and the main barn is to the left and ends just equal with the back of the house.
There is a space about 20 yards from house to barn.
Now in the center line of that space. We had a wood pile to feed the fire pit. Against the front of the wood pile, and open to the street (about 50 yards from the woodpile) we let the weeds grow as a a view blocker of the pit area.
One year I set out a 25 gallon potted GHOST OG plant and said nothing.....I just had to see who would notice... We also had various plants numbering around 16 spread around in the lilly's and bedding plants.
Of everybody coming over to party or dine. The bulk of the hidden plants were seen by everybody at some point.....
The now 11ft tall plant (The roots traveled into the ground from the pot's air/drain holes", out in the open and in plain sight....Was discovered by only a very few. Even while it budded!
Those who did find it. Saw it when looking back at it, when at a bonfire and not at all when standing by it or walking past to go to the fire pit...
Keep them in plain sight and in an area where weeds naturally have been.....
