‘Chartreuse on the Loose’ is a perennial with season long interest perfect for lining the front of the border. The foliage allows for a full three seasons of interest with bright chartreuse yellow leaves. Clusters of lavender blue flowers are produced just above the foliage and appear all summer long. Unlike most catmint, ‘Charteuse on the Loose’ will continue to produce flowers without being cut back.
When Nepeta’s stems are broken, they release an aroma into the air that tends to attract cats, thus its common name, Catmint.
