My yard used to be (I'm in a condo now) a plant zoo. The variety of plants you can use as camo are almost endless. Big plants like Castor bean (poisonous) will draw attention away from MJ but beans on poles or Morning Glory/Sweet Peas on trellis can add height where you need it as well (don't over shade your herb garden). Keep in mind you will want MJ strains that don't go over 3-4 feet or train them to grow more horizontal. Cleome is another lookalike that can be placed more prominently as a distraction, the leaves are similar but the flowers are different. Lots of variety and colors distracts the eye away from some hidden herb so plants like large Dahlias, Canna lily and Glads will provide lots of mid/late summer blooms. Many ornamental plants are poisonous, I had to warn a neighbor that just nibbling on leaves in my yard was not a survival trait. Digitalis, Aconitum, Ricinus were just a few of the killers in my yard (that and my shovel). Even with these and many other plants in my yard I only kept a few special plants in my greenhouse before moving to remote locations, just too many looky-loos around.
