Catnip
Nepeta cataria
Catnip's psychoactive effect on cats is triggered by nepetalactone, an iridoid compound that activates feline olfactory receptors in a way reminiscent of pheromones — about 60% of cats inherit the genetic sensitivity from their parents; the other 40% are immune.
How to care for catnip
Plant in a sturdy cage or protected spot if outdoor cats roam — they roll on it, chew it, and destroy young plants within weeks. Self-seeds aggressively; cut spent flowers before seed sets. Drought-tolerant once established.
