Catmint is one of our "top three" perennials. Aromatic silver-green foliage. Periwinkle-blue flowers over a long blooming season. Trim back after each bloom to encourage faster rebloom. Deer and rabbit resistant. Drought tolerant once established.
A common complaint lodged against catmint is that it can grow larger than people want for smaller spaces. Junior Walker is the answer--a compact variety that only grows about 15" tall. Zone 5. Full sun.
