(75-85 days. Nepeta mussinii) Catmint forms a low-growing mound of fragrant foliage with spikes of 12 inch violet-blue flowers. If planted early in the season, it will bloom the first year. It is a perennial that blooms like an annual. The foliage is vigorous and spreads to a width of 10 – 12 inches. Catmint plants work great as a general ground cover, accent plant, pathway edger, rock garden specimen or in the herb garden. Like catnip, Nepeta Catmint attracts cats, and its flowers furnish nectar for hummingbirds and bees. Can also be used in tea for sleeplessness and nervous tension.
