Nepeta nervosa "Blue Moon" (Catmint)
Nepeta nervosa "Blue Moon" was a pleasant surprise in my seed tray this past winter. I immediately liked it for its foliage: slender, textured, and gray-green. Then, spikes of clear blue flowers appeared, and I knew I had a winner. The butterflies totally approve and, although I haven't tried the leaves on my cats yet, I expect they will, too. Nepeta nervosa "Blue Moon" forms a dense clump and grows from 12 to 16 inches in full sun and well-drained soil. It is perfect for borders and will continue to bloom if you are mindful about dead-heading. Zones 5-9. Quarts.
