Catnip flower spike
A common problem for folks TRYING to grow fresh organic catnip for their feline friends is protecting it FROM cats, theirs and others, that will buzz a plant down in minutes. Solution? Grow it in hanging baskets they can't reach. Catnip is very easy from seeds. When I lived in Denver I noticed soon after moving there in the fall of 1987 that it does SO well there it reseeds to the point of being seen as a noxious weed. Here in Tampa it does best as a winter annual when the climate is cooler and drier.
