Plants for garden security

These are some common shrubs that are both colourful and very prickly to touch. These security plants are a natural deterrent when placed near walls and fences that intruders may try to climb over.

Do not underestimate these security plants - they are very sharp and should be planted responsibly - away from children and public places.
