When I saw the attached article, my first thought was to plant them as a safety perimeter around the home to safeguard against potential nasty types (humans). One of the plants is stinging nettle, which (when harvested properly) can be used in salad or made into a tonic. Anyway, just thought it might be helpful to someone(s). http://ca.shine.yahoo.com/photos/plants-to-avoid-when-hiking-or-camping-in-canada-slideshow/
Might be OK until the kids get into it. I think I prefer a dog or two. Reminds me too much of the Day of the Trifids.
Hog weed being Hog weed are you not worried about it creeping in and takeing over the garden ??
The rest of the world is trying to stop the spread aren't they
Not a gardener , just wondering
Actually, I was thinking of the stinging nettles and devil's club more than the rest, since they do double duty: deterrent for burglers (if planted around windows and trimmed back as needed) and can also be used medicinally.
Personally, I go for blackberry bushes.
They present a pretty darn good barrier that even bears do not like to go through, and the berries are delicious.

Great idea - but don't they require a lot of sun? Most of the plants mentioned in the article can be grown anywhere. Of course, making blackberry jam and wine are a great incentive as well.

We have blackberry bushes not far from our place. I've been considering transplanting some onto my property. I hadn't thought of useing them as a barrier. Now I think I know what I can use to fill in the dead ground around my place. Thanx Capt A.
Those who are unwilling to defend freedom, will become unfree.
As a perimeter defense plant I would go with Hawthorne or Japanese rose bushes or for that fact any creeping rose bush will do. A long creeping rose stem (still attached) buried will start a new bush. Better deterrent than barbed wire, believe me, I have the scars to prove it. 😐

One more thing, roses are carnivores, and need protein ( my mom use to bury a carp in her rose garden every year). If you don’t believe me, look at the thorns, and which way they are the pointed, inward or outward.
